DMA is enabled and I have an XP2400+ with no other large CPU loads, so the
CPU shouldn't be a problem.  This line here leads me to believe that there
is no encoding going on:
Writing AVI header...
Pos:   0.0s      1f ( 0%)   0fps Trem:   0min   0mb  A-V:0.000 [0:0]

The error saying that the buffer is full follows this.  It seems like the
capture component is working, but the encoding part is stuck on something.

My understanding was that the btaudio thing was only for capture, so if I
unplug the line from my soundcard to tv card, I won't get any audio when
viewing.  Having said that, I don't know why the card would be sending
audio data to it's line out while I was using the onboard capture feature.
 Any ideas?
