Oh I agree that DVI is being used in the TV market to eventually lock in the signal and keep people from being able to record whatever they are watching on TV, but I beg to differ with you about the conversions not degrading the signal.

There is signal loss, but it depends on your source and your system. If you have even one set of DAC's that the signal has to travel through that does not have greater or equal number of bits of resolution, the signal will loss quality. And it does get converted back and forth through the systems. Depending on the A/V receiver, it might just do a plain pass-thru of the signal and not convert it, but it will still get converted once off you DVD player and once back in your TV (this is assuming your are using a HD TV or HD ready TV, but it you have an old analog one, then this won't affect you).

For instance, if the origional signal was produced using 32bit digital cameras (Lucas Arts used this when filming the new Star Wars movies), the origional source is in 32bit resolution for color and brightness. If your DAC's are only 24bit, your reproduced image will be slightly off. Instead of your final image using a possible 4,294,967,296 colors on the screen, it will only be able to show 16,777,216, which is a pretty big difference. This also assumes that your TV can actually represent that many colors on its screen, so if you do not have a TV that can represent it, then to you, there will be no difference in what you see, but compaired to the origional source, there is a difference.

"Digital features" was just a short way of saying whether or not the TV was capabile of using the digital signal. I should have just stated that instead, as it wasn't the best terminology.

The overall image will be determinded by the weakest link in the chain that does any conversion from digital to analog or vice versa.
