at 2200Mbps w/ mp3 audio, my files come out at almost exactly 1Gig per
hour.

at 4MBPs, it should be ~1.8Gig per hour.  So yes, something looks screwy
with your file sizes.

(Just so you know, the transcoder ignores the width/height and audio-rate
that you set in the Transcode profile.  Actually resizing the video or
resampling the audio would require a bunch of math I have no interest in
coding up.)

Anyhow, I can't explain the problems you are seeing, but I will look into
them now that I am back home, and see if I can figure out what is wrong.
