Recently, when my Cox Communications cable service realigned some channels, I lost HD service to some key sports channels I enjoy. I receive the audio stream, but not the video. This problem only happened with the channel changes (moving HD from 700s to 1000s channel numbers). First a little technical background on my equipment.
I have a circa 2004 Mits CRT "big box" set that uses a cable card. I have had all known software updates to the card. Call me stubborn, but I believe when you purchase a TV, you shouldn't have to rent a outboard tuner for the rest of your life... However, that's another rant, back to the reception issue...
After replacing my one-way cable card, and trying to get a two-way card to work, the technician now says that it is a native format issue with my set... he explained that the sports channels in question are delivering their signal in 720p...and he says, my set can only display 1080i.
OK...maybe...but I know that the local Fox station transmits in 720p as does the local PBS station, and there may be others...I get their pictures just fine.
Am I getting accurate information? Naturally, I'd like to continue to use my cable card rather than having to rent a "box."
