We have recently joined Netfix.  My wife wanted to watch a movie on Netflix last night.  However after downloading MS Silverlight and trying to make the movie play.  We got the 
Digital Rights Management (DRM) Error
Error Code: N8156-6003
So I phoned Netfix customer support and got bad advice.  I got bad advice four times.  So then I researched it on the NET.  I found this is a bad problem that they have never fixed with Microsoft, and has to do with their system not working properly with Windows 7 64 bit.  If anyone else has this problem, then 
this advice works first time.  However after discovering and implementing the fix, it was time to go to bed!
So I tried to help Netfix, with an online chat this afternoon.  You will see not many neurones and synapses firing in Latoya's head.  Here is our chat.  You can LOL all you want.
Netflix                         Latoya                                          Hi there, my name is Toya. Am I chatting with Denise?
                                                                                                                  55 minutes ago                         You                     
                     This is the correct procedure for handling the issue with MS Silverlight and your site.  It is Mark on the line, her husband.

                     I was given bad a advice by customer support four times yesterday.
                              
                                                               53 minutes ago                         You                     
                     Your issue is not Microsoft's fault, as your system does not work properly with Windows 7  64 bit.  You have not moved beyond 32 bit.
                              
                                                               52 minutes ago                         Netflix                         Latoya                     
                     Hmmm, well we definitly want to get this issue resolved so what is the error message you get on you windows 7 Mark?

                     The one everybody has been getting.  Digital Rights Management (DRM) Error Error Code: N8156-6003
                              
                                                               51 minutes ago                         You                     
                     Actually I was given bad advice four times.
                              
                                                               50 minutes ago                         You                     
                     The method in the link I sent you worked perfectly first time.  The advice to delete the files given by Netflix is harmful.
                              
                                                               49 minutes ago                         Netflix                         Latoya                     
                     Well I apologize for the miss information give me a moment to look this up and take a look at the link you were given please.
                                                   
                                                               49 minutes ago                         You                     
                     I was not given that link, I found the site.
                              
                                                               47 minutes ago                         Netflix                         Latoya                     
                     So what steps beside deleting a file have you done on your computer?
                                                   
                                                               45 minutes ago                         You                     
                     I followed the  instructions in that link I sent you.  I started my browser in  administrator mode, restored the deleted files under a new name, Removed  silverlight, reloaded it, saving the exe file to the hard drive.  Then  I went to Netflix with the Firefox browser still in administrator mode  and I could see the movie, but then it was time to go to bed.
                              
                                                               44 minutes ago                         You                     
                     The operating system is windows 7 64 bit, on my HTPC in my state of the art home theater.
                              
                                                               40 minutes ago                         Netflix                         Latoya                     
                     Hmmm, Ok so have you deleted the mspr.hds file from your computer?
                                                   
                                                               39 minutes ago                         You                     
                     I was told to do that, and I did, but restored it from the recycle bin and renamed it, as per the advice in the link I sent you.
                              
                                                               34 minutes ago                         Netflix                         Latoya                     
                     Gotcha ok so this link in  the neflix database for the error you received has most of the steps  that you have already done. Except it doesn't say to restore it here is  the link which im sure is similar to the one you had  
Click Here . Try deleting it without restoring it

                     I do not want to delete  it.  That file is there so I can play DRM protected downloaded media I  have and will pay for.  You CAN NOT BE TELLING PEOPLE TO DELETE THAT  FILE!  I have everything working. I'm just informing you that nobody at  Netflix knows what they are doing.  We are new customers and finding out  the Netflix is a bottom rung crummy outfit.
                              
                                                                                                                                                                                                               29 minutes ago                         Netflix                         Latoya                     
                     These are the steps that  we have received to resolve this issue. I have had tons of people follow  these step and delete that file without restoring it and there netflix  and all other programs still run properly.
                                                   
                                                                                                                                                                                             28 minutes ago                         You                     
                     I have already sent that  link and the advice is not correct even though it comes microsoft.  The  real answer, I have found out is that Netfix needs to write new  software, so your site works properly with Windows 7 64 bit, not just  the 32 bit version.
                              
                                                                                                                                                         28 minutes ago                         You                     
                     Your software team needs a kick in the rear, and told to fix this problem.
                              
                                                                                                                                                                                                                                                   26 minutes ago                         You                     
                     You don't get it.  The  computer needs that file to be fully functional.  Also having the  browser in administrative mode is crucial to fixing this problem.
                              
                                                                                 25 minutes ago                         Netflix                         Latoya                     
                     The error you are  receiving is a silverlight error which is produced by Microsoft.  Silverlight is the platform that we use to run netflix on the website.
                                                   
                                                                                                                                       24 minutes ago                         You                     
                     So instead of telling people to delete the file, they need to be told to rename it.
                              
                                                                                                                                       24 minutes ago                         Netflix                         Latoya                     
                     So Mark once you put your browser in administrator mode does it not stay?
                                                   
                                                                                                                                                                                                                                 22 minutes ago                         Netflix                         Latoya                     
                     If you don't want to  delete that file there is a picture of a man next to some words that say  Microsoft fix it you can select him and run the fix it tool.
                                                   
                                                               22 minutes ago                         You                     
                     According to my best  research it is not microsoft's problem, but a problem with Netflix and  Silverlight not running properly on the 64 bit platform.  It is a  problem for both of to work together on this.  You are loosing a lot of  customers over this.  The Net is full of a lot of your very unhappy  customers.
                              
                                                                                                                                                                           20 minutes ago                         You                     
                     I know and the fix it  tool says to rename the file and not delete it if you want your computer  to stay functional.  But the crucial step is to have the browser in  administrative mode, otherwise the file will reload corrupted on a 64  bit system.
                              
                                                                                 18 minutes ago                         You                     
                     You need to fix this so  all the customer has to do is to press the silverlight download button,  that comes up when you first try to stream a movie.  That should be it.   It should be as seamless as possible for your customers.  They don't  want a geeky solution.

                     Ok Mark I understand your concern give me a brief moment to look into some other things.

                     Okay, so the mspr.hds is a  temporary internet file and it won't make any negative impacts to  Silverlight or computer if you delete it, however if dont want to these  are the troubleshooting steps that we receive from Microsoft, since it's  their software if you are concerned the best thing to do is c get in  contact with them and see what else can be done!

                     I don't care as I have  solved it for me.  I will give you one last piece of advice.  You are  the ones who need to beat microsoft up.  If they don't fix it I suggest  you switch to Flash Player.

                     I have heard flash player  would better to use maybe we can switch to that one day if we continue  to have these issues. I am definitely glad you are able to watch you  netflix.
