They can output those modes, meaning you can spit out a 480p or 720p 
progressive scan signal to your HDTV. But just because they can display 
those modes doesn't mean they can decode an HD stream. It simply means 
you can have a nice 1280x720p modeline outputting everything to your HD 
display from your X-Box Linux system. For example, I output a 960x540p 
signal from my MythTV box through a VGA->Component Video adapter for 
everything (desktop, shell, mythfrontend, dvd playback, etc.), but 
that's just the video signal, it isn't an HD stream. I can decode an HD 
stream and display it over that signal, producing a very good picture, 
but my processor is an Athlon XP 2600, and is being heavily taxed by 
that process.

Long story short, being able to do an HD display mode doesn't mean you 
can decode HD content. The X-Box is more or less a PIII-733 with a 64MB 
GeForce 3 and 64 MB of system memory, if my own memory serves me right. 
Linux takes advantage of it as well as it can. The system just flat-out 
doesn't have enough juice to do anything HD. DVD, yes, but DVD is about 
1/4 the resolution of a full HD stream.
