However, if you try to mount it as UDF, it says something like "can't find a superblock at the end of the image". If it's supposed to be UDF, then the first thing I'd try is to dd the whole thing to a file, then run fsck.udf on that file, and see if that can reconstruct the superblock or at least make the first few VOB files readable. Note that the fsck you need may be called udffsck, and it might not be installed. The fsck for UDF should be available on all distros. It may also be that it was burned as a multisession DVD and never fixated, or it had 2 sessions and the second session was messed up. "cdrecord -toc dev=/dev/scd0" will tell you how many sessions it has. > try to get some details from her brother about how he > made it. I doubt that she will be able to. If the DVD is damaged at the very edge, where the fs said it was looking for the superblock, or there's multisession oddness going on, that could cause the problems you reported. -- Matt G / Dances With Crows The Crow202 Blog: http://crow202.org/wordpress/ There is no Darkness in Eternity/But only Light too dim for us to see > On Thu, Sep 13, 2012 at 8:02 AM, Matt Graham wrote: > > > > > Are you sure this is actually a DVD, and not something weird like a > > DVD-sized > > SVCD?
