I have one file that plays very jerky and keeps buffering on ATV2. I stream via Ethernet. It plays just fine on my computer (also streaming) but plays terrible on my ATV2. This is the only file I have problems with. I notice the CPU is significantly higher when playing this file, 92-96%.

The name of the file is Madagascar 2 Escape 2 Africa 720p.

"16 frames"

That's the problem. That's an absurd setting, and whoever encoded the video doesn't know what they're doing.

[modenacart]

That would drive the processor usage? Why does it play well on the computer?

[Ned Scott]

The hardware decoder won't accept it, so the CPU tries to decode it but doesn't have enough power. The reason your computer plays it well is because it's a big desktop computer that runs an actual desktop CPU and not a cellphone CPU like the ATV2.

[modenacart]

Should I re encode the file?

[Ned Scott]

If you want to watch it on an ATV2, sure.

[modenacart]

are there recommended settings and is there a good shareware program?

[Ned Scott]

Handbrake (wiki) and most of its profiles are fine, such as the HighProfile settings.

Thanks.
