Hello, I have a problem with burning DVD-Video on a DVD-RW media. Burned discs won't play on most software and hardware players. While it plays in Windows Media Player, it won't play in VLC on Windows, neither VLC or Xine or Mplayer on Linux, and won't play on any standalone player I tried.
I usually burn DVD-R media, which works OK, but this time I am trying to master a DVD with family videos, which is the reason why I have choosen -RW media. I started investigating the problem, as the other option would be a landfill of wasted DVD-Rs :) When I try to play the -RW disc on mplayer, or xine, or vlc, the following lines appear in terminal: libdvdread: Using libdvdcss version 1.2.9 for DVD access libdvdread: Could not open /dev/dvd with libdvdcss. libdvdread: Can't open /dev/dvd for reading So I tried again with DVDCSS_VERBOSE=2: libdvdcss debug: opening target `/dev/dvd' libdvdcss debug: using libc for access libdvdcss debug: disc is scrambled libdvdcss debug: requesting AGID libdvdcss debug: ioctl ReportAgid failed, invalidating AGID 0 libdvdcss debug: requesting AGID libdvdcss debug: ioctl ReportAgid failed, invalidating AGID 1 libdvdcss debug: requesting AGID libdvdcss debug: ioctl ReportAgid failed, invalidating AGID 2 libdvdcss debug: requesting AGID libdvdcss debug: ioctl ReportAgid failed, invalidating AGID 3 libdvdcss debug: requesting AGID libdvdcss error: ioctl ReportAgid failed, fatal libdvdread: Could not open /dev/dvd with libdvdcss. libdvdread: Can't open /dev/dvd for reading The line "libdvdcss debug: disc is scrambled" caught my attention. After a bit of digging in libdvdcss sources, kernel sources, and MMC commands documentation, it seems to me libcss gets the information that the disc is protected by sending "READ DISC STRUCTURE" command to the drive, and the drive gets it from the disc. Nero Infotool recognizes the protection as "CPRM". Is it somehow possible to remove this protection? I noticed in MMC documentation, that there is also "SEND DISC STRUCTURE" command, and you can send some "Copyright Management Information" with it. Couldn't it be used to mark the disc as not protected? Best regards -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
