dvd backup

rip dvd with dvdbackup (pool/bin/dvdcopy). burning this with mkisofs
gives problems with region encoding.. so trying to re-mux it like this:

 vobs2iso GATTACA2/VIDEO_TS/VTS_01_[1-4].VOB

looks like dvdauthor can take stream input. using this:

dvd_copy () {
    mencoder -dvd-device "$1" dvd://1 \
        -oac copy -ovc copy \
        -of mpeg -mpegopts format=dvd:tsaf \
        -o "$2"

a title in the dvd can be transcoded to a .vob file, which can then be
fed to dvdauthor to re-author a dvd image. the author itself needs
disk access since it's 2-pass.

hmm.. mencoder can't generate to a pipe..

so. dvdbackup + mkisofs works fine to remove encryption, but the
resulting dvd will still be region-specific. to remove this, the only
thing i was able to make work is to use "transcode dvd_copy" and

hmm.. vob files are really just split at a fixed size, so
concatenating them should work?
