Thank you for the link, that helped explain a lot of what I was seeing.
I have mythtv setup on the high quality capture to grab 8000 kbps, 384
kbps audio, and dvd stream type. Before I upgraded to 0.4.1 driver my
average capture was running about 6,000,000,000 bytes for an average
movie of 1:45:00, now that same time average will yield a file size of
12,000,000,000 bytes on average.

I have made one change to the above, I set dnr_temporal to 0 as I
remember reading on a mythtv setup guide that I should do that. I
have not yet made a capture, but when I do I will report on the size.
I guess that I should also find out exactly the noise and median
filters do. Any suggestions where to look?
