Tried multiple dvd drives. dd if=/dev/sr0 of=dvd.iso bs=2k always results in dd: reading `/dev/sr0': Input/output error 1+1 records in 1+1 records out Tried on sr1, and sr2 all fail in the same way. And yet the movie plays just fine with vlc and smplayer!! This the first time I see this. I never had this issue on Fedora.
