how about this for a bummer:
was trying to watch [on my "new" Cox DVR w/chasing playback] the FOX broadcast of Packers at Ravens, followed by NO at NE yesterday on my 50 inch 1080i projection TV (vintage 2002).
i selected component input, pressed play, and poof: no video, only audio! had to switch to the SD composite input to display ANYTHING! called Cox cable in Fairfax, VA and they said to
try other HiDef channels, which I did, e.g., CBS nfl game was coming in fine on the 1080i component input display. WTF? Cox must have a video cutoff if a feed is too weak/noisy. Then when the MLB playoff game came on at 830pm sunday nite on fox, the hidef 1080i tv picture was magically visible again! so i had no hidef video for both Fox nfl games on that DVR to TV connection. maybe fox has started 1080p hidef broadcasts for nfl only? or experimenting? my 1080i component display should support any hidef broadcast up to 1080i, but not 1080p, unless Cox downcoverted the signal?
