I think that was me posted the dance clip, and yes seconded: you
couldn't wish for better playback than from these little devices. I
recently found some H264 (High 10) videos which the graphics chip
doesn't support and they played perfectly even though decoded on the CPU.
I use mine just as a frontend. It sounds like you are running it as
front and backend combined. Interesting. What sources do you have and
what capture devices?
