I heard that none of the next gen DVD formats will support 1080p. If that's true it sucks.
Molly asked us if we (the listeners) knew of High Definition content available on DVD, Windows has some cool HD content available for purchase. I have not bought it yet but plan to just to check it out. I think you have to play this on a Computer (which is not a big deal for me since I have a HTPC) since there is no DVD player (as far as I know) that can play native 720p or 1080i/p without up-conversion.
Note some of it does not have any DRM!!! Go M$!
