Post subject:  Can't play DVD's
My KnoppMyth R5A16 install has stopped letting me play DVD's Dunno what I did, but I could ceratinly play DVD's last night. Have been trying to get MythTV playing on TV (works fine on monitor) so I've been mucking about with XF86Config, but don't think I touched anything else.

It's not the symlink prob that's been raised before:

Code:
root@mythtv:~# ls -al /dev/dvd /dev/cdrom /dev/scd0 /dev/hdc
lrwxrwxrwx  1 root cdrom     8 Jul 12 10:22 /dev/cdrom -> /dev/hdc
lrwxrwxrwx  1 root cdrom     8 Jul 12 10:22 /dev/dvd -> /dev/hdc
brw-rw----  1 root cdrom 22, 0 May  7  2004 /dev/hdc
brw-rw----  1 root cdrom 11, 0 May  7  2004 /dev/scd0


When I try to run xine as root in xterm it actually opens the player, but when I go to read a DVD it gives an error that says:

Code:
The source can't be read.
Maybe you don't have enopugh rights for this, or source doesn't contain data (eg disc not in drive).
(/cdrom/video_ts/vts_o1_0.vob)


The when I exit xterm it has this in it:


Code:
*** libdvdread: CHECK_VALUE failed in ifo_read.c:669 ***
*** for pgc->cell_position_offset != 0 ***


*** libdvdread: CHECK_VALUE failed in ifo_read.c:649 ***
*** for pgc->nr_of_programs <= pgc->nr_of_cells ***


*** libdvdread: CHECK_VALUE failed in ifo_read.c:667 ***
*** for pgc->program_map_offset != 0 ***


*** libdvdread: CHECK_VALUE failed in ifo_read.c:669 ***
*** for pgc->cell_position_offset != 0 ***

ASSERT ERROR: file util.c: line 174 (to_bcd8): assertion failed: (n < 100)



I don't think it's a permission issue, myself.

Code:
root@mythtv:~# grep mythtv /etc/group
cdrom:*:24:mythtv,mwishart
audio:!:29:mythtv,mwishart
video:!:44:mythtv,mwishart
mythtv:x:105:


Any ideas what need to do to fix this?

Thanks
Mick

Have you checked out the doc files included on the system? Look carefully in the directory /usr/share/doc/libdvdread3/examples. I think you'll find everything you need there.

Thank you!! That was the issue. The DVD I tried the night before mustn't have been encoded that way (it was a local Soapie episode). :roll:

Thanks for taking the time to help.

Cheers
