Playing DVDs

[st89]

I gathered from OpenBSD Faq 13.9 (can't post link) that it's possible to play DVDs, with or without mounting them. When I do

$ xine /dev/cd0c

I get

- xine engine error -

Input plugin failed to open mrl'/dev/cd0c'

and behind that another message saying

"sight", unknown error. (Permission error /dev/cd0c)

I then do

$ sudo chmod a+r /dev/cd0c

which takes away the second permission-related message but still leaves the first. I then do

$ sudo mount /dev/cd0c /mnt/dvd;
$ xine /mnt/dvd

and can hear the DVD drive whirring and reading the disc before getting

- xine engine error -

Input plugin failed to open mrl
'mnt/dvd/VIDEO_TS/VTS_03_0.VOB'

...which leads to Xine hanging up and requiring killing.

I have similar problems when trying to use dvdrip in that mounting works but reading directly from the DVD drive doesn't. Does anyone know of any resources to get 'raw' (i.e. no need to mount) DVD playback/ripping working? Thanks in advance for any help/tips/pointers
