How can something so unhelpful be a feature?
See if both channels have the same amount of noise, the one that's 
noisier *will* be bigger. rtjpeg is more sensitive to signal noise than 
MPEG-4, and its file sizes aren't as constant. With my MPEG-4 settings, 
I get about 217Megs +/- 5 megs per half-hour, whatever the channel or 
the noise.
