I'm pretty sure that you need write access to the (real) DVD device as
well. A good way to do that would be to create a group named e.g. cdrom,
and add yourself to that group. Next you need to set the following in
/etc/devfs.conf:=20

own     acd0     root:cdrom
perm    acd0     0660
link    acd0     cdrom
link    acd0     dvd

What video output are you using? If supported by you graphics card
driver, use the xv video device (vo=3Dxv in ~/.mplayer/config).

The config looks OK.

Are those the binary-only windows codecs? I've always run mplayer with
"none" in those preferences. Works fine here.
