Very cool, I will be sure to try that right away.

I have to think that there will be... If nothing else, than because
NVRec is designed for recording from a TV-card, and does a good job of
things like buffering data (for 1sec by default) before writing to disk.
With nuppelrec, I can record 640x480 video and (I assume it uses) PCM
With mencoder, using MJPEG for video is just about as
processor-intensive as mpeg4 (maxes out my XP 2000+)... I assume that
is due to lack of (or poor) buffering (although any other explanations
are welcome!). If I use any lavc video codec (mpeg1, mjpeg, mpeg4,
rv10, h263), and PCM audio with mencoder (even mono--even at a sampling
rate of 24000) after a minute I get constant messages about dropped
audio frames... That's on a 7200RPM HD, btw.
