Denon 3805 issue

DVR 8000 and Denon 3805 video problem

(also posted in interconnects - hoping someone who ownes a Denon may catch this here)

Here's my problem:

I am trying to hook up video through a Scientific Atlanta DVR8000 cable box yellow video out to my Denon 3805 receiver yellow video in, and upconvert the signal to my Toshiba 36" CRT which has Color Stream or R/G/B inputs. I am not getting a picture. I had one at first, then it started to flicker. Now I am reading on page 10 of the Denon manual that I may need to connect a "commercially available video stabilizer with a time based corrector". Are they assuming a VTR is a DVR, or are these two different animals? Is this an issue because this DVR is running off a hard drive constantly for the record and pause functions? What a waste of technology if that is true. This DVR8000 dinosaur still has composite and S Video hookups, so I could really use the Denon's video upconversion here. I just switch cable companies for a better deal on cable and internet. Some deal. I may just go back and use the coax straight to the tv. Anyone run into this before?

Anyone? I've never heard of a video stabilizer with a TBC time based corrector. I am currently just running the coax to the tv from the DVR for now, but ran a digital out from the DVR to the Denon digital in for audio. Sounds great.

I am not having this problem. I'm upconverting my TiVo using regular RCA composite video. The component upconversion to my tv works great. This is also working fine for my GameCube.

We have very simular equipment

I'm running a SA Explorer 8000 DVR and a 3805 also. I'm running S-video from the 8000 to the 3805's TV s-video input. For audio I ran a digital coax cable from the 8000 to one of the 3805's digital coax inputs. Then component video from the 3805 to my Toshiba 57" RP CRT. In the setup menus I set the TV video to S-video and audio input to coax 1. Everything works fine for me.

Sometimes I like to listen to a CD during commercials so I ran a yellow composite video cable from the 8000 and a toslink digital audio cable from my CD player to the 3805's VDP input. I set the VDP audio input to one of the toslink inputs and the video input to composite in the setup menus. I can switch to the VDP input and get CD audio and 8000 video. Again this setup works fine for me. The difference between the 8000's S-video and composite video outputs can easily be seen this way.

I would check the video input mode in the 3805's setup menu to make sure the input you are using is set correctly. Look on page 41 of the 3805's manual for more info.

Hope this helps.

That makes sense. I think I will try an S video hookup instead of the yellow to yellow. I also don't remember seeing the option S video in the setup menu. That's probably the issue.

Cmusic, do you notice any better picture when routing the video through the 3805?

I did notice a much better picture running the video through the 3805, but I think the 3805 is not necessarily is the reason for the improvement.

On my Toshiba TV the composite (yellow) and S-video inputs are much brighter than the component video (Colorstream) inputs. The colors are also more washed out. I noticed the difference before I got the SA 8000 and 3805 when I tried the different video outputs from my DVD player. The Toshiba's component (Colorstream) inputs have a better picture, much better color and resolution than the S-video or composite video inputs. The 3805 does not necessarily improve the picture when converting it to component video, but more importantly it does not hurt it in any way.

When switching between S-video and compostite (yellow) video from the SA 8000 the S-Video's reolution and sharpness is greatly improved. Color is very close to being the same, but S-video has a slight advantage here also.

Cmusic,

My 36" Toshiba CRT has the colorstream inputs on the rear, along with 3 video inputs and two antenna inputs. Right now I have the coax from the 8000DVR to antenna 1 coax in on the Toshiba. Can I use the colorstream inputs with the component outputs of the 3805 for everything and bypass the antenna and video? I thought the picture would be better using the coax of the DVR8000 to the tv directly as opposed to going S video to receiver to colorstream. I thought Toshiba recommended the colorstream inputs for dvd only. Man does HDMI sound good now.

That's how I have my system set up now and love it. The 3805 switches the sound and video in about a second. I can switch audio and video from TV to DVD to my Playstation 2 in about two seconds.

The output resolution from the 8000 is 480i, which is the same as using a non-progressive scan DVD player. The TV should not care where the signal is coming from as long as it is something it can use.

Before I got the 8000 and 3805 I used the component video outputs of a Direct TV reciever into the colorstream inputs for about two years with no problems.

Man does HDMI sound good now.

Unfortunately my TV was made the year before Toshiba added digital video inputs (DVI and HDMI) to thier TVs.
