With DishNetwork and either the 622 DVR or 722 DVR you can support two separate TVs or do a PIP on a single TV. I know this doesn't directly help in your case, but does you HD DVR box support more than one TV? If so, the addtional TV output possibly could be connected as the PIP. Surely DirecTV has something similar to DishNetwork; if not, it could be a negotiation leverage item with DirecTV.
Good Luck.
Thanks, I had heard of that I just could not work it out. I have the Direct TV HR 20 HD DVR and the latest HR 21. They do not support two TV's.
To use his PIP feature he will need an additional satellite box.
I checked the standard receiver and it does not support PIP or two TVs. It requires one line from the multiswitch.
So he will need three lines in all to do what he wants. Two from his HD DVR and one from the HD receiver he will need to run PIP.
This is probably not what he wants to hear.
The other thing is that Direct TV equipment is very fragile, and taken out by SMALL variations in power voltage, especially even brief periods of low voltage. This includes the phantom powered LNB units and multiswitch.
I have both my units supplied by online UPS units with VERY fast response times.
Originally I had one unit on a UPS but not the downstairs unit. I had to add one for the downstairs unit to stop it blowing up and blowing up the multiswitch and LNB units. Since I did that it has been plain sailing. Those Direct TV units redefine low price point manufacture, I can assure you.
