	I had a quick look at what has happened to the capture code in
mplayer since I last saw it (and felt a bit ill). It seems that it pretty
much depends on the frame sync signals from the bktr device with a fallback
one second alarm. I know that missing frame sync signals are not uncommon
from instrumenting my capture code in ffmpeg which is kept sane by using
a tightly timed usleep to capture a frame close ot the right time when the
signal is missed.

	I'm guessing that enabling the audio capture is causing signals
to be missed.
