</div>The iPad does have hardware acceleration. If it did not, you wouldn't be<br>
able to play much of anything due to lack of any significant FPU<br>
performance in the ARM chip. The iPad's video decoder is the same one<br>
found in Intel GMA500 units, capable of HD MPEG2 decoding but artificially<br>
limited by Apple. The XBMC devs released a version at the beginning of the<br>
year that uses an undocumented video API that should allow hardware<br>
accelerated MPEG2.<br>
<br>
If you want to transcode due to network throughput or storage constraints<br>
on the iPad, check out:<br>
<a href="http://www.mythtv.org/wiki/Transcode_wrapper_stub" target="_blank">http://www.mythtv.org/wiki/Transcode_wrapper_stub</a><br>
Give it the command you want, and configure it as a user job. It will the<br>
whatever command you define, delete the old copy of the file, update the<br>
path and filesize to match the new file, and flush the seektable.<br>
