Polo13ca,

From what I can tell, it looks like Xine is looking for your DVD device, which I think, is that MRL message... I cant help you with Xine, I use Kaffeine, which uses the DVD device /dvd, and the libs from Xine...

I would jump into your settings in Xine, and see if you can locate the MRL you are getting the error for, and check what device your DVD is actually as, and then change the MRL to that "correct" MRL...

I also read, before I moved to the v3.4 Knoppix, that Xine was having problems in that version, which is why I moved from Xine to Kaffeine when I hard drive installed Knoppix v3.4 - you may also try doing a Search Knoppix.net for Xine, and see if this problem has come up before, maybe someone else has gone through the exact same issue, and has gotten some resolve or reasoning of what the problem is, and how to correct it

Hope this helps,
Ms. Cuddles
