Hi, I'm sending this e-mail to both Ogle und Mplayer mailing list since it concerns both. A friend of mine is using libdvdread 0.9.3, libcss 1.2.2, Mplayer0.90rc4 and Ogle-0.8.5 . When trying to play a DVD with mplayer or ogle he gets the following error: libdvdread: Can't seek to block 256 libdvdread: Can't open file VIDEO_TS.IFO. Can't open VMG info! I have read a thread on both groups where this behaviour was reported before, but there was no solution :-(. ( http://mplayerhq.hu/pipermail/mplayer-users/2002-September/021173.html http://lists.berlios.de/pipermail/ogle-user/2002-June/000545.html ) We set up everything like this: chmod 666 /dev/hdc ln -s /dev/hdc/ /dev/dvd We did not tweak anything with hdparm. We then compiled both libdvdread and libdvdcss and did a "make install" The drive is a Matshita SR-8587. We even looked for another firmware for the Matshita and installed an RPC-1 from http://forum.rpc1.org/dl_firmware.php?category=1&manufactor=18 That also did not make the problem go away. I can mount the DVD-ROM with UDF and ISO9660 and can always see whats on there but mplayer and ogle cannot play it. btw: When we use a Lite-On LTD 165-H instead, everything works just fine. André.
