The ATV2 does not support hardware acceleration of the MPEG2 output by a
digital tuner, nor the HD MPEG4 output by mythtranscode. That means you
are relying on the woefully inadequate 1GHz ARM for software decoding.
Until XBMC has fully explored the VideoToolBox API and documented what
the device is actually capable of, rather than what Apple has restricted
the device to, the only authoritative reference on the decoding
performance of that device is on the Apple site.
