This must be the third wasted DL DVD.  I think that I will need to
concentrate on transcoding the darn thing from now on.  I wish I could
pin point the problem.  When I tried playing the DVD in M$Windows it
complained about the region not being set - but I didn't have any such
problem in Linux.  Nero express won't even see the DL disk, just shows
the size of CD.  Could it be something to do with the firmware?
