Define "can't read." Does it mean that it says "no media in" or does it say "no superblock" or similar. Try to run dvd+rw-mediainfo against DVD-ROM unit (yes, against DVD-ROM, not recording unit) with this recorded media in. > dvd+rw-mediainfo gives me that output: > > # dvd+rw-mediainfo /dev/cd1c > INQUIRY: [DVDRW ][IDE1008 ][0054] > GET [CURRENT] CONFIGURATION: > Mounted Media: 11h, DVD-R Sequential > READ DVD STRUCTURE[#0h]: > Last border-out at: 0*2KB=0 > > The "Last border-out at: 0*2KB=0" seems weird for me, but maybe I'm > wrong. It *is* wierd and it *can* limit playability in legacy units, at least in those which explicitly support DVD-R playback (those which support exclusively DVD-ROM look at "legacy lead-out" value and disregard "last border-out"). It's most likely your burner firmware deficiency [at least other recorder units are known to exhibit sane border-out values] and the question is if there is a workaround for it. Things to try: 1. Try to leave media opened for multi-sessioning and see if "last border-out" is sane then. To perform -dvd-video recording and leave media open you have to split mkisofs and growisofs as following: mkisofs -dvd-video /path/to/video | growisofs -Z /dev/cd1c=/dev/fd/0 Submit dvd+rw-mediainfo output for resulting recording. If "last border-out" is sane and media still remains unplayable, fill it up with 'growisofs -M /dev/cd1c=/dev/zero'. Submit dvd+rw-mediainfo output for resulting recording. 2. Try to perform DAO recording by complementing growisofs command-line with -use-the-force-luke=dao option. Is recording playable then? Submit dvd+rw-mediainfo output for resulting recording. > If I burn the same thing (using the same command: growisofs -Z /dev/cd1c > -dvd-video /path/to/video) on a DVD+RW, the result is readable... Session closing code for DVD-dash and DVD+plus recording is completely different and success with DVD+recording doesn't exclude possibility that there is no bug in DVD-dash code of your unit firmware. > Another thing, when I want to burn a data DVD I have to avoid the > -dvd-compat option or the DVD will be readable only by the burner. Well, this basically provides answer to the above suggested experiment #1, because -dvd-video implies -dvd-compat. Can you submit dvd+rw-mediainfo output for such "data" recording? I write "data" in quotes, because from the actual recording point of view there is no difference between "data" and "video" input, it's all just data.
