Seems God doesnt want you to watch them
The programming really is the thing. Half of the HD miracle is smoke and mirrors.
One of my friends added a room onto his house for a home theater, has the tiered seating, all the big speakers and a top of the line 1080p projector. He's tried comcast HD and directv HD.
Most of the channels arent in HD. Of the ones that are, only some of the programming is in HD. Of those, some are upconverted SD and some are lower 480/720 HD. And the quality of the actual HD stuff is varied by the cable/sat company lowering the supplied bit rate for each channel to allow more channels in the same bandwidth.
When we switched from the AFC game to the NFC game yesterday, it was obvious that the AFC game looked a lot better, so was probably getting a higher bitrate. He said you cant watch anything in HD on friday and saturday nights that isnt a PPV movie, because they give all the bandwidth to those so they look good...same problem on saturdays and sundays during the day because it all goes to HD sports.
And with cable, the first 99 channels still remain analog and unless theres an HD version of it on the upper channel tier (like ESPN and ESPN HD), you wont get any better picture than you're getting right now. In fact, on some HD sets display an analog SD picture looks worse than the same channel on an old analog set.
