Not sure if this is the right spot, but I think a DTV rep might have just told me a way to get rid of the non-HD cables nag screen. Pardon me if this is an already known solution, but it's new to me. In the Settings/Display/TV Resolutions, uncheck every resolution except 1080P. 1080P needs to be the ONLY resolution checked. Setting it up that way, I get HD on my HDMI output for my main TV, plus I also see output on the S-Video (what I have going to my PC-TV card in another room) and I no longer get the nag screen. Also have Settings/Display/Video/Native set to Off. Seems like it's working OK - and I don't see the nag screen anymore on my s-video connection. This work for anyone else?
