In the NTSC world, there was a clear difference in picture quality that you could expect from variou sources. In general, DVD is better than prerecorded VHS tape, which is better than recording from broadcast or cable onto a blank tape.
However, as I understand, in the world of HDTV, there will be no difference in picture quality between recording from satellite onto a blank D-VHS tape or hard disk recorder, and prerecorded D-VHS, and HD-DVD. If that's the case, why would anyone buy a prerecorded tape or HD-DVD, if for a fraction of the price, they just can record from satellite and get the same quality. Am I missing something here?
