Hi,
I am new to this forum. I have XBMC on my old xbox and decided to get an appletv last week right on the day XMBC and Boxee was possible on it.
Anyway I found that the video tends to stutter a bit (?dropped frames) especially on high action scenes. MKV is slightly worse. On Boxee it is fine. I prefer XBMC at the moment for offline videos (Not supported on boxee)
Any suggestions? I thought of reducing the quality of video but will take some re-encoding, if so what is best settings? I thought maybe I can tweak something in XBMC to make it run better.
Thanks

I've tried playing and MKV via a network share and an the MKV on the ATV. Playback with both is very "unsmooth".
The same video played on a PopCorn Hour A100 has no issues.

Same here, 720p MKV plays well most of the time but gets jumpy when there is a lot of action. I'm on 100Mb wired LAN playing media on a SMB share.
Any settings we might tweak to get smoother playback?
I'm back to original xbox and AVI files for a while I guess.

make sure the software upscaler is off.
I would need to get a sample of the video content to see if you are seeing a user setup issue or some other issue.

Same thing here on all 720p MKV TV shows downloaded.... it accelerates through frames for about a half-second, then continues playing smoothly for about 5 seconds, then restarts again the accelerated frame rate. Endless loop.

I doubt anyone can help me since before I even reached this thread I was coming to the same conclusion as Davilla, but for the record, this is what mkvinfo is reporting:

So, can anyone confirm that this is unplayable on an first gen AppleTV due to its complexity, and further, is there any way I can watch this without spending 24 hours recoding it (i.e. on the order of a 24:1 ratio on conversion)?
