They overcompress the TV signals horribly. If you don't think so, look at an uncompressed over the air HDTV signal and compare it with what you get on cable or satellite. Would you be willing to pay more for uncompressed HDTV?

I haven't seen any difference. Cable HDTV channels look the same as over the air channels.

If it looks good to you, don't worry about it

This isn't an issue with your TV, its the signal going to the TV. Its like the difference between using a regular old standard definition composite video cable vs. component/dvi/hdmi - the TV is the same, its the signal thats not as good.

I thought this thread was going to be about people not knowing the difference between SD and HD signals. The other day, I was at my favorite barber shop when I noticed they were watching the SD version of our local ABC station on their 50-inch plasma TV. The barber shop has cable and our local cable has HD, so the only reason I could figure was that they just didn't know any better.

It's not a matter of needing to pay more. The systems are using compression because they simply don't have the capacity to provide additional full-bandwidth HD channels. This problem will solve itself in 2011 when cable systems are allowed to stop sending bandwidth-hogging analog channels over their systems. Freeing up the analog channels will eliminate the crunch that's forcing cable to use compression.

2012 - and thats not necessarily the cut off date either, there will be a review by the FCC. Which seems odd to me anyway, as the FCC really shouldn't have the ability to control cable companies, they don't have the required percentage of customers, last I checked.

Anyways, thats not the problem anyway. Satellite companies have a very widespread offering, and in order to keep up, most cable companies are over-compressing to shove more channels into their line up. As a result, most are going with about 75% resolution (ie: 75% of SD resolution, but without noise, many viewers aren't really going to think its worse). In other words, its happening because the cable companies have made a decision to compress to damn near VHS quality because it lets them show how many channels (even though most suck) they have, which is why you as a consumer should go with cable instead of satellite or fiber.

Or don't like it because the HD channel frequently doesn't fill in on the sides. I find the sides of the picture missing to be annoying, myself.

I agree with StillwaterTownie's assessment.

My mom had Cox cable and the digital and HD channels looked very chunky to me on the 30" widescreen LCD that I bought for her. By contrast, I have a 46" Sonia Bravia LCD and I have a Dish Network HD-DVR and the HD channels on Dish Network are flipping awesome. The quality is an order of magnitude better than traditional cable. I suspect this is because the satellite has a much wider "pipe" and can fit more content through without as much compression and quality loss.

I don't have this problem but I've seen that before. Most players and TVs can be configured to avoid this behavior.

Honestly, if I was stuck with traditional cable HD, I'd stick with a modern analog TV, like a used rear projection CRT TV (the CRT is important because its analog whereas LCD or DLP projection TVs are digital). Analog sets make the screen artifacts caused by compression more tolerable.

If you had traditional cable and really wanted better quality HD then I'd investigate Dish Network. I'm sort of an early adopter and I've had nothing but a pleasurable experience with DN's HD-DVR players.

I'm really happy with HD technology. After 7 years I recently upgraded our home video camera from our trusty Sony Digital-8 to a Sony HD recorder with a built-in hard drive. The quality is amazing. Once the Blu-Ray and HD-DVD battle sorted itself out, I bought the LG Blu-Ray burner for my PC, and the Panasonic Blu-Ray player for my TV. So now we can burn our family home videos to HD. I've been pretty jazzed about that.

I have low-def eyes...I don't need a high-def signal.

The stretch-o-vision solution makes people look abnormally wide. I'd rather see the black bars than see everyone look like linebackers.
