Acidrip has been my Linux DVD ripping program of choice going on several months. Unlike OGMrip, Acidrip seems to get audio and video synchronization correct. Unfortunately Acidrip isn’t perfect. Some DVDs, like Crank, just do not rip correctly. Enter dvdbackup. Dvdbackup backs up DVD structure and files and it seems to do the job even on difficult DVDs like Crank.
When I first used dvdbackup I used the -F switch which backs up the main feature of the DVD. When I ran dvdbackup -F the program created a directory named CRANK along with several files: an IFO file and several VOB files.
I was able to watch the movie by adding a few of the VOB files to Totem. When I tried to play the CRANK folder with XBMC it wouldn’t play anything. XBMC has no problem playing ISO images. Dvdbackup indicated that it’s possible to get movies backup up with the -F switch into a playable format using the dvdauthor collection of command line tools, but when I checked the dvdauthor web page it doesn’t appear to be a true statement.
At this point I ran out of time. I’m sure that I’ll figure out the next steps. For now this is a good start to backing up those difficult DVDs.
but unfortunately even dd does not seem to copy movies like CRANK. (dd makes a sector by sector copy)
