If I use # mplayer dvd://1 it does work but it is so slow that it is unacceptable. The transfer rate is only a little more than 1MB/sec, and this does not seem to be right for I am using USB 2.0. I found the following in the dmesg when I plug the DVD device: umass0: Prolific Technology Inc. Mass Storage Device, rev 2.00/1.00, addr 2 cd0 at umass-sim0 bus 0 target 0 lun 0 cd0: Removable CD-ROM SCSI-0 device cd0: 1.000MB/s transfers I don't know why the system says cd0 is only 1.000MB/s, and I don't konw whether this is the cause of the bad performance in playing DVD. If I mount the DVD and use $ mplayer /cdrom/video_ts/*.vob the performance is dramatically better. I don't know whether the improvement results from the use of system cache or from some real improvement in the transfer rate or from both. However, this does not work for region-code protected DVDs. I tried to use # mplayer -dvdauth /dev/cd0 /cdrom/video_ts/*.vob as suggested by the manual page of mplayer but failed. I kept getting DVD: opening libcss.so as libcss.so ... DVD: dlopen: Shared object "libcss.so" not found Error in DVD auth... Exiting... (Fatal error) Since libcss seem to be no longer available, does anyone know how to solve this? Can't libdvdcss be used instead? Any suggestions?
