HP was supporting blu-ray but now is supporting both formats since the blu-ray won’t support iHD like HP asked them to. Although blu-ray has more the majority of movie studios with them, most of the technological companies are now backing HD-DVD or both formats.
The only thing that will make blu-ray a success is tha fact that its gonna be included in the PS3. Lets see how this all turns out I’ll stick with my old trusty DVD since blu-ray supports the same MPG2 codec DVD does I highly doubt there will be any diffrence :-/
