That's actually a good idea, though I'd probably do it the other way around
(CBR for shows/movies and VBR for sports and maybe documentaries).

The defaults on the HD-PVR were ...

Low Avg - 4,500, Low Max - 6,000
Med. Avg - 9,000, Med. Max - 11,000
High Avg. - 13,500, High Max - 20,200

Quality vs. Filesize ... for stuff I watch right away I don't really care
about filesize, but I also have stuff that sits around unwatched for a long
time (I have some recordings almost a year old) and for those I'd rather
have smaller file sizes.
