I have an older U-verse receiver with DVR - Model Number IPN4320-SG-A. I also have a U-verse wireless receiver Model Number ISB7005. I want to be able to use both receivers in the same room with two HDTVs so I can watch two sports events at once without having to use PIP. However, both remotes are controlling both boxes so I'm unable to view different programming on both. Is there some combination of remotes that I can use that will alleviate this problem? I don't mind buying new remotes if there is some way to have them each be dedicated to a specific receiver. Oh, and even if the wireless receiver and the small TV are being used out on the deck, the remotes still conflict between the receivers. Thanks!
