Use the attached script to find your recording profile details, i.e.:

mysql -umythtv -p mythconverg < recording_profile.sql > results

For comparison, the values I use are value at the bottom of this post. 
It gives basically VCR quality recordings that are 1.15GiB/hr.  Really,
the AvgBitrate should probably be 4500 and the MaxBitrate should be 6000
for best quality (anything higher--for either--is wasted bits), but I
chose quantity over quality (the source is low quality, anyway).  The
stream type is critical...
