I am playing back an MP4 video on the ATV and it is out of sync with occasional stuttering/slow playback. Sometimes the video will stop and rebuffer which does not happen anywhere else on the ATV.

Typically I play rips of DVDs in the Video_TS format and not MP4

I am sure that it is something small as this video has worked fine a couple of times. I had to rebuild the ATV recently due to an issue with itunes sync so this is a reinstall of 9.04

Thanks!

I think that the MP4 might have been encoded at a rate that the ATV can't handle. I re-encoded it into an m4v file with default apple tv settings with handbrake and it works well now.

That said I am curious to know what the pastebin says.....if there is some optimization that I am missing.

Turn off upscaling and pick a different renderer setting, you are renderering with software (SW) and that's very slow.

OK Thanks! What is the recommended renderer setting?

I don't have upscaling turned on that I am aware of.....would it try to upscale if I have the screen output set to 1080i?

Thanks for the help!
