Subject:   Failure to read a Bluray disk with 'dvdbackup' command
Message-ID:  <5702C29A.5050208@rawbw.com>

Next in thread | Raw E-Mail | Index | Archive | Help
My attempts to backup a Bluray disk with this command fail:

# dvdbackup -M
libdvdread:DVDOpenFileUDF:UDFFindFile /VIDEO_TS/VIDEO_TS.IFO failed
libdvdread:DVDOpenFileUDF:UDFFindFile /VIDEO_TS/VIDEO_TS.BUP failed
libdvdread: Can't open file VIDEO_TS.BUP.
Cannot open Video Manager (VMG) info.
Mirror of DVD failed

System log gets this message repeated many times logged  during 
dvdbackup command:
