I really don't have any problem with the existence of D-VHS and have finally seen a demo of it.... I was very impressed with the video quality....
I'm a DVD guy so I won't invest any money into D-VHS/D-Theater. As for HD-DVD, I'm very cursious to see how that takes form. I've heard that HD-DVD won't "match" D-VHS' video capability (meaning it might not support anything greater than 720p), but that should still be a GREAT improvement over existing DVD....
There is HD-DVD discussion
here.
Peace.....
