For you Handbrake fans, I found a .deb file created by Fraser Murray that fixes all of the various problems with upgrading. You can download it here. To run, do:
cd /data/usr/local/bin
ghb
I think it's being installed in the incorrect directory, but it seems to work pretty good. The new Handbrake seems to be quite speedy compared to the old version, though I haven't checked out how the encoding fares yet.
