dvdbackup generates huge copy
[ Maybe this is the same bug as bug#648920, but I don't understand that one enough to judge. ]
Viewing a DVD in my favorite way is paradoxically inconvenient since it involves copying the DVD to a machine that doesn't have an optical drive. So dvdbackup is a very good friend of mine.
But recently it has let me down a few times, because the VIDEO_TS folders it generates for some DVD are much larger than they should. E.g. it might generate a 60GB folder for a perfectly normal (at worse dual-layer) DVD. The result works (VLC plays it just fine), but the extra space is problematic, both in disk space and in network-transfer time.
In case it's relevant, I'm using Debian's dvdbackup-0.4.1-1 package and I'm usually very pleased with it.
