hi Lawrence,<br>

Agreed - this basically reflects my minimal MP4 playback testing
too.<br>
<br>
I didn't test mkv playback in any way as comprehensively as Rob
though.<br>
<br>
I found that 720p h.264 is enough to make it stutter, turning on
subtitles (ass / sub station alpha format) is enough to kill it.<br>
<br>
FWIW mythtv seems to render subtitles in real-time. With a suitably
fancy font, and say karaoke-like font animation, even a workstation
has troubles. On the same hardware, vlc does not.<br>
<br>
I made a test sample, I just need to get it out somehow.<br>
<br>
cheers,<br>
