No, that's exactly my point: it seems like it's probably too slow
everywhere. And as it turned out I made a 1-line fix that resulted in
a major optimization. Still not enough to make HDTV playback look
good, but it's a start.
The frontend was doing a terribly slow regexp creation/search sequence
in TV::GetQueuedChanNum that was soaking 14.6% of the process' CPU
cycles.
