libdvdcss error, can't play DVD's :-( any ideas?
I've been trying to get my box to play DVD's, but instead receive some
interesting errors. I have no idea what's causing this, but I think it might
have to do with the way I have the drive mounted. Any DVD player I try like
mplayer, ogle, etc will give me this same error, so any ideas? I have a
feeling the libdvdcss can't lock on properly for some reason and is then
giving that seek error in the logs below.

I mount the drive with (/etc/fstab):
none /mnt/cdrom supermount
dev=/dev/hdd,fs=auto,ro,--,iocharset=iso8859-1,codepage=850,unmask=0 0 0

[root@localhost chris]# ogle /mnt/cdrom

First, MythTV doesn't contain any DVD player, so you're offtopic.
Second, try mounting the dvd the usual way, not via supermount
Third, try to open /dev/hdd directly using ogle, I think it can read
unmounted disks.
If all that fails, you probably have a hardware or kernel problem.

Is this due to the legality issues surrounding DVD players / DeCSS on
Linux?

Nope, it's rather due to the fact that I consider software DVD playback in
linux pretty sub-par when compared to a real DVD player. That said, it's
extremely easy to add a button to the menu to launch another program (ogle,
mplayer, xine, whatever) to play DVDs.

Make a symlink /dev/dvd -> /dev/hdd. Don't bother mounting the disc; just
start up the player like: 'mplayer -dvd 1' or such.
