Why does DVDA want to compress my HD video files?

I rendered some video with a few of the HD templates in vegas under the mpeg-2 option. When I go to make the DVD, DVDA says it will recompress all the rendered clips that were rendered as HD, no matter the format (ie-30p, 24p, 60i). I verified that it wants to recompress the video, not the audio. When I rendered the same clip as anything that wasn't HD, it showed the green check mark next to it.

Why would it have to recompress HD when DVD's can play HD?
thanks,

DVD's might be able to support it, but you aren't going to be able to create HD dvd's with consumer/prosumer equipment at this time.

Sonic's latest version of Scenarist supports it. There is a new format war brewing for HD dvd's. One camp is looking at using a new compression scheme (mpeg4) to fit ~2 hours of HD material on standard dvd media. Another is looking at using mpeg2, which would require much higher capacity discs than are currently available (except to a relatively small number). It uses a different laser technology (blue-ray), and can hold 20-30 gigs on a single layer disc (which is needed for 2 hours or so).

For right now, the best you can do is output HD type files and burn them to a dvd as a data disc. You could then view them on your computer, but you won't be able to have menus, chapters, and the like.

thanks, all this HD talk got me a little too excited I guess.
