This may habe different reasons: - The drive does not read the medium (DVD+R/RW has not the best quality for exchanging between different drives). - The OS driver tries to mount the medium from a wrong start sector # - The OS filesystem does not support the right UDF version for real time video. > I have unsuccessfully tried the following: > > + cdrecord -fix > + growisofs -dvd-compat -M /dev/cd0=/dev/zero > + the "close.cpp" program from Andy Polyakov If you just fixate the medium, it is unlikely that you get any advantage. > luigi# cdrecord dev=1,0,0 -minfo > Cdrecord-ProDVD-ProBD-Clone 2.01.01a52 (i386-unknown-freebsd7.1) Copyright > (C) 1995-2008 Jörg Schilling > scsidev: '1,0,0' > scsibus: 1 target: 0 lun: 0 > Using libscg version 'schily-0.9'. > Device type : Removable CD-ROM > Version : 0 > Response Format: 1 > Vendor_info : 'ASUS ' > Identifikation : 'DRW-2014L1 ' > Revision : '1.00' > Device seems to be: Generic mmc2 DVD-R/DVD-RW/DVD-RAM. > Using generic SCSI-3/mmc-3 DVD+R driver (mmc_dvdplusr). > Driver flags : NO-CD DVD MMC-3 SWABAUDIO BURNFREE > Supported modes: PACKET SAO LAYER_JUMP > WARNING: Phys disk size 2295104 differs from rzone size 15872!

There is a second track that is currently been written to. I cannot tell anything about the file system data structure inside these tracks..... readcd f=/dev/null sectors=0-15872 and readcd f=/dev/null sectors=15888-1225952 should both give no errors on your system. If you verify this, then the problem is the filesystem on the medium....
