a friend of mine whos a real a/v guru has managed to burn a full DVD movie in 1080i (a dual layer DVD9 is good for about 90 minutes in 1080i), so im wondering if it would be possible for XBMC or some other app to play this in full resolution, or if there is some hardware limitation (im not sure if DVD decoding is done in hardware or software on the xbox, im assuming software)

I am gonna get one of the disks to try for myself, but i thought id ask on here first

I'll let the others chime in, but the short answer is no.
I'm sure a modded xbox 360 will do it though!
We just gotta get that thing modded when it comes out!

I tried to play a 1080 on my XP PC (2.0Ghz Pentium 4) and it was pretty much a skip-a-thon...
The xbox has a 733Mhz processor. Kind of puts it into perspective...

Get the IODATA AVEL LINKPLAYER 2. Cost me $250.00 I can stream all kinds of HD Content to it or put them on DVD's to play in it.

List of HD supported.
TS, WMV9, HD-MPEG2, DivxHD

All the way up to 1920x1080i 27meg plus streams. Unit was well worth it.

Its like the HD version of X-box without the games. But I hope Xbox 360 will allow for HD streams as well.

yeah i believe my friend said he burned it as HD-MPEG2.

So, youre saying that XBMC *should* be able to recognize it and output 1080i, but it would just be really jumpy.

The thing todo in a situation such as this is to just try it! Then report back on what is/isn't working and maybe there is a solution or maybe it just won't work, but like I said best thing todo first is try it out...

despite that my comp had a hissy fit trying to play the chip i just downloaded (it was a movie trailer in 1280x720p), xbmc played it fine. It was jumpy in a few spots, but increacing the cache of vids played from the HDD from 256k to 1mb fixed it.

I couldnt find anything of small size ( <500mb ) in 1920x1080i, but the 720p test seemed successful.

It will be a different story when playing from a dvd, but so far im hopeful it will work.

I can help out here. No, the xbox will not be able to play the hd-mgep2 file. I've tried it before. I've captured some shows from my HD-Box and tried 3 different methods and copied them over to the xbox for testing purposes.
One file was the ts file directly (1080i mode recording). Wouldn't even play.
2nd file i re-encoded that file to 1080i xvid (in case it helped with speed of xbox unit) played choppy and every 2 seconds it paused a sec.
3rd file i re-encoded the original file to 960i (which was 960x600, vs-1080i which is actually 1900x1080) and about 96% quality in Xvid format, and it played just fine. Anything higher then those settings will play but not smoothly and will also pause every couple seconds. And gets worse with each higher settings. Boosting the cache only helps a little.

Still looks much better then any DVD out there in quality, but still not quite as sharp as 1080i. The video i used was a 'Pink' concert on HD-HBO one day i recorded.

Hmm well mine played the trailer i had in 1280x720p great, it only paused once or twice in the whole 3 minutes, and upping the cache fixed it.

My only question: yes, XBMC will play these high-res videos, but is it actually outputting in 720p or 1080i or whatever? I tried messing with the menu on my TV but i couldnt get it to tell me what input it was getting.

Well, depending on what format your 1280x720 video was done in (MPEG,AVI/Divx/xvid) I suppose one type might play a little better then another.
I personally spent a good 5-6 hours trying each compression level and resolution until i found one that worked the best, which is what i mentioned above. Since all xbox are the same (meaning there's not enough differences in hardware to cause a speed difference), it shouldn't be any reason to get the different performance levels.
But 1900x1080 (1080i) resolution video's in mpeg2 are not possible on the xbox. I'm saying this because of personal experience with trial and error. 1280x720 video's could play ok but that's not 1080i which i thought was the original question.

Now, the output would be 1080i upscaled if you had it set right in settings. It does look great also on my mitsubishi 56inch 16x9 HDTV. Hope that helps out.
