It doesn't degrade the image quality, no more so than using a 56K modem instead of a 28.8K modem causes your data to get garbled.
Hi,
I don't want to open Pandora's Digital HD Box here, but there has be a great deal of discussion on bandwidth compression by cable providers so more programming can be offered at the expense of image quality. However, this seems to affect only some channels and can be traced to poor source material in some cases. This was the basis of my comment. Personally, if there is bandwidth compression, I haven't noticed it, but others have.
