I haven't found much info on the Xbox for HDTV playback. Any ideas here? It does give you component output. Will it do both 720P and 1080i? With the XBOX 360 out now the prices should drop on the old systems.

In a word: No.
The XBox has no where near the CPU horsepower to play HDTV.

Cessman, to clarify your point

Q: Does XBMC and Xbox support HDTV (High Definition TV) resolutions?, and HDTV media?
A: Yes and no, but the answer is a little more complicated than that, you see: Xbox/XBMC can output 480p/720p/1080i (if you have a High Definition AV Pack/component cable) and upscale all low-resolution videos (like retail DVD-Video/Movies) to 720p (1280x720 pixel progressive) or 1080i (1920x1080 pixel interlaced) in hardware (linear upscale/upconvert). So XBMC have no problems with upscaling example DVD-video (720x480 NTSC/720x756 PAL) movies to HDTV 480p/720p/1080i. XBMC is even capable of playing native HD video (video/movies with native resolutions higher than 720x576) like 720p (1280x720) and 1080i (1920x1080), however there is here a big snag/limitation and that is that a standard Xbox only has a 733Mhz Intel Pentium-III CPU (processor) and that does not have the processing power to decode those native HD video resolutions, and that means you would only get maybe 10fps (frames per seconds) displayed which would appear so jerky because of all dropped frames that it will be un-viewable. The only solution if you want to play videos with native HD resolutions on Xbox is to buy or upgrade to a non-standard Xbox with a much faster CPU (processor), (like example the DreamX-1400 from FriendTech which has a 1480Mhz Pentium-III that is at least capable of decoding native HD videos that are have up to 720p in native HDTV video resolution. FriendTech do offers trade-in). Note! XBMC does not yet have DVD-menu support so note you only get video on DVD-Videos. Note! You must enable/setup your HDTV settings in Microsoft dashboard, (on NTSC Xboxes).
To make this even clearer XBMC capability on a standard Xbox (with Intel 733Mhz PIII CPU):
- 720x480 pixel video output to 480p HDTV (720x480 progressive) = OK! (eg not upscaled).
- 720x480 pixel video output to 720p HDTV (1280x720 progressive) = OK! (eg upscaled).
- 720x480 pixel video output to 1080i HDTV (1920x1080 interlaced) = OK! (eg upscaled).
- 1280x720 pixel progressive video output to 720p HDTV (native 1280x720 progressive) = FAIL!
- 1920x1080 interlaced video output to 1080i HDTV (native 1920x1080 interlaced) = FAIL!
Note! All above that state FAIL don't actually fail to play, it's just that the Xbox CPU is to slow to decode/render the high resolution so it will drop so may frames that is will be un-viewable.
PS! There are not many standalone DVD-players out there that can even upscale normal DVD-movies to 720p or 1080i and those that can are much more expensive than a modded Xbox ;-P
FYI; Microsoft® & DivX® recommend 2.4 Ghz PC + 384MB RAM for 720p MPEG-4 playback!

I'm sorry, in my mind upscaling isn't the same as playing HD. The answer remains the same. Don't be fooled by the technobabble folks... BTW: There is only one s.

What about using the XBOX 360 as a front end to stream HD content? Free60 has successfully loaded linux onto the 360, but I have not found if anyone has put MythTV on one yet. Has anyone done this or tried?

I keep thinking that this uPnp stuff is going to make the 360 a no-brainer front-end. i.e. it should just "find" the videos and recordings, and play them. As should Vista. But it doesn't seem to work. Whatever MythTV is offering via uPnp, doesn't seem to interest the 360 and Vista. At least, not for me. But I may be doing it wrong...

This may depend on the version of the backend - newer ones may have better compatibility.

I haven't done any UPnP testing (don't have the hardware), but the PS3 apparently works OK* with the current (SVN head) backend.

(* there is one bug I know of - recordings which are named in Japanese don't display with the correct names on the PS3).
