[mythtv-users] Bit rate oddity?

[Michael Williams]

My variation is MUCH larger. I have recorded 2 1 hour shows, one was
near 9 gigs and 1 was less than 3 gigs.  Sure, the picture was a little
noisy on the 9 gig one, but with that much variation, I would have
imagined the 9 gig one would be unviewable, but its not.
