That is very similar to the error I got with ogle. I vim as root the oglerc file (I forget exactly where it is, can post tonight when I get home to my machine). And about 15-20 lines down there is a line the states dev=/dev/dvd or close to that. I swapped that to /dev/cdrom and it played.
And just to be dumb here you do have libdvdcss and libdvdread installed (you get them at the ogle site) don't you? Just noticed there is a later version of libdvdcss. It's 1.2.2.
I haven't got to symlinks and things yet so I'm just editing at the source.
I think it's to do with the way especially earlier dvd players were designed as DVD/CDROM combo.
