Suppose 'dvdbackup -r b' (skip blocks) is run on a scratchy disc. It
runs for a while, finds some scratches, and accordingly slows down.
After an hour or so, it's done some useful work, (halfway through the
worst scratch we'll imagine), but the drive is needed for another job.
'Ctrl-c' stops 'dvdbackup', user swaps the disc, does another job,
comes back, reruns 'dvdbackup' and -- 'dvdbackup' throws away all the
work it did before:
The menu file /mnt/stuff/ac//SUFFERIN_SHAD_DISC53/VIDEO_TS/VTS_01_0.VOB exists; will try to overwrite it.
The title file /mnt/stuff/ac//SUFFERIN_SHAD_DISC53/VIDEO_TS/VTS_01_1.VOB exists; will try to overwrite it.
The title file /mnt/stuff/ac//SUFFERIN_SHAD_DISC53/VIDEO_TS/VTS_01_2.VOB exists; will try to overwrite it.
Something like the a 'wget' '--continue' option would be good.
Hope this helps...
