More data:
Tried two movies that I streamed to the ATV using Home Sharing.
They actually also hiccup sometimes.
But they do hiccup more when playing from XBMC, especially when the pictures change more, e.g. when one scene fades into another one.
But when streaming from iTunes the CPU is 65% idle (6% AppleTV, 16% mediaserverd).
When watching the same movies through XBMC the CPU is only 42% idle (~50% AppleTV, 2% mediaserverd).
For comparison I bought aTV (black) and CPU usage is also much lower at 65% idle (27% AppleTV, 2% mediaserverd).
It also has a hiccup occasionally, but less often than XBMC. I think it's comparable to iTunes streaming.
Could this be a spike in CPU utilization, running out of pre-rendered buffered frames?
Are there any background processes in XBMC that consume extra CPU? Missing hardware acceleration?
Possibly this is gonna be better on the ATV3 (more RAM, A5 chip), but it's not jailbroken yet, plus I still want to use my AV2
