Oh, and BTW artguy, the difference between DVD scaled well and HD-DVD isn't the jump that VHS to DVD was, you can see the comparison right now if you want - go grab a D-Theater player (DVHS) which is actually higher quality than either of the proposed HD DVD standards (HD-DVD and Blu-Ray).
The D-Theater titles are noticable better, especially a title like I-Robot. The difference between it on DVD on a standard TV and the D-Theater title on a HDTV is very pronounced, but the difference between the DVD through a terranex on a HDTV and the D-Theater title through a HDTV is more subtle than stunning.
