[mythtv-users] Bit rate oddity?

Having used Myth for a couple months now, I have observed that the
filesize of recorded video seems larger than it should. I have it set
to record at the default values using MPEG 4 -- 2200 Kbps and Audio MP3
Q7 (whatever bitrate that works out to be), resolution 480x480.
However, the resultant files are between 3-4 GB for an hour of TV. Now
according to my calculations, at 2200 Kbps the video portion of the file
should be slightly less than 1 GB, and the audio should be comparatively
small. So I have to wonder, why the heck the files are so big?
Has anyone else observed this, and if so what is the reason?
Thanks,
John
