Hi, are you really sure that the medium is DVD-R DL and not DVD+R DL. DVD-R DL is said to be incapable of multi-session at all. I never bought one. So i cannot tell what my drives would offer to do with them. I would be interested in seeing the output of
dvd+rw-mediainfo /dev/sr0 The 4GB-check-problem is obviously in the loop beginning at growisofs.c:2990 for (i=1;i<argc;i++) The interpretation of no_4gb_check happens inside this loop rather than after it. if (dev_found && in_device) ... if (/*(mmc_profile&0xFFFF)<0x20 ||*/ ((mmc_profile&0xFFFF)<0x40 && !no_4gb_check)) Of course one would have to check carefully whether it is ok to move this whole interpretation out of the loop. An interesting question is why the the check is disabled for Blu-ray media: ((mmc_profile&0xFFFF)<0x40 The problem tackled by this 4 GB check is in old Linux kernels (and still in modern FreeBSD) which take the byte address of the directory record (inode) as 32-bit inode number. So if the directory tree is stored above 4 GB, the inode numbers roll over and inodes are not found any more. This mount problem does not depend on the media type.
