Sure they have them in the specs but are commited to MPEG-2 right now,well at least initially.
First, it's a STUDIO's option to chose to put their content out in MPEG-2 or MPEG-4. The players for both High Def Media will support both. And remember that the discs are simply Media, you can put whatever the hell you want to on them. It's a matter of what the player standards support, and what the content providers put on them.
As far as MPEG-4 vs MPEG-2 superiority debate goes. What do you care if the Image Quality is as good in MPEG-2 as it is in MPEG-4 but takes a larger amount of space. It's not like your storing this on a HDD (yet anyway
I'm sure we'll be ripping them soon enough - you can always crack a nut if you got a big enough hammer)
The big deal on MPEG-4 is not superior quality, but lower bit-rate for the same quality. This is why you see Satellite providers moving towards this because of limited bandwidth, their sub-banding of HD Channels requires them to overcompress the data until it looks like crap. You're not seeing cable go this route because they have plenty of bandwidth.
At the current highest quality terestrial broadcasting of HD we're at 19Mbps with MPEG2. A BluRay capacity is 25GB on a single layer disc, that's almost 3hrs worth of video of 'Discovery Channel HD' Image quality.
Now, take those numbers and convert to a 15GB single layer HDDVD and you get under 2hrs for MPEG2, but you can get the same quality using MPEG4 with less space.
Think about it, HDDVD capacity is effectively requiring studios to go strait to MPEG4, while BluRay capacity gives the studios a choice.
