On this note, I have done some playing around and added this line to my 
/etc/rc.local on my RH9 system (I have some other test_ioctl functions 
above it).  This setting results in almost exactly 2GB an hour files, and I 
have noticed no quality difference between it and the default setting.

# Turn down the sample rate for smaller files - about 2GB/hour
~jac/ivtv/ivtv/utils/test_ioctl -c bitrate=4000000,bitrate_peak=10000000
