I've jailbroken my AppleTV and it's working good except one issue. Whenever I record HD programming from TV using MythTV, when I trancode to x264 mp4 files, I often prefer to de-interlace certain types of programming down to 720p60 (60 frames/sec) rather than the more conventional practice that most people seem to use of de-interlacing all the way down to 30 frames/sec. This preserves the smooth, hi-motion/video look that I like. These h264 mp4 files work perfectly on XBMC on my HTPC (Dual-Core Intel and VDPAU nvidia GPU), as well as my PS3. XBMC plays them back with the same perfectly silky smooth hi-motion video look of the original tv broadcast on my HTPC and the PS3's own video player does the same too. However on the AppleTV2, even with the hardware decoding, XBMC just can't seem to handle it. Hi-Motion 720p60 recordings play back at half the speed (30 frames/sec) on the AppleTV2, so everything appears in slow-motion and a video simply plays back for twice as long.

Is there any way to get the AppleTV to play back 720p60 smoothly or is simply beyond the hardware? AppleTV2 seems to work great for low-motion telecined material (23.976 fps), as well as video content that's been de-interlaced down to 29.976 frames/second progressive.

ATV2 can't handle 1920x1080 @ 23.976 (1080p24), this looks to be hardware limitations, I think 720p60 would be just as hard on the hardware as 1080p60 is.

PS cropped 1080p is fine, I've played back plenty of 1920x800 files and have no issues.
