OK, some but not so much progress. As it was suggested that I connected the drive to another PC, so I connected it to my Ubuntu 16.10 64 bit desktop PC. In this PC I already have 2 dvd drives which both play any region dvd just fine. The first drive /dev/sr0 is a hp DDVDW TS-H653R which has no region set The second drive /dev/sr1 is a ATAPI DVD A DH16A6L-C which is locked to region 2 by default (4 changes left) The problem drive (from the HTPC) /dev/sr2 is a MATSHITABD-MLT UJ265 First thing I noticed with /dev/sr2 is that regionset says has no region set even though I set it to 2 on the HTPC. Also ubuntu says there are 5 changes left not 3 like my htpc box said. If I put any encrypted (any region) DVD in /dev/sr0 or /dev/sr1 it plays without question. I have watched many DVDs on this PC in the past with no problem. If I put the DVD in the problem /dev/sr2 when I press play it tries to load for a second but stops. I tried VLC / mplayer and ubuntu's video player. sr0 and sr1 play fine sr2 stops (although it does play blu ray discs no problem). I have tried purging libdvdcss2 and clearing the ~/.dvdcss folder but this made no difference. I also tried an unencrypted DVD (a home movie) and this plays on all 3 drives. So this confirms it to be a problem with my specific drive. (or so I thought). I then connected it to a windows PC (for the first time in over a year). And tried WMP and VLC and it bloody works just fine !!!!! I only installed VLC on the windows PC today from the videolan website which had libdvdcss2 install included. Thoughts on why this one drive will not play DVDs? I suspect perhaps it could be the drive firmware and that VLC in windows is ignoring the drive's firmware and just playing, but in linux for some reason the firmware of the drive is locking out playback? I heard that this used to be a massive problem years ago (if that is true then I can see why piracy has been such a big problem in the past if you legally buy a DVD and cannot play it). Does anyone know how to check the drive firmware version? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
