dvdread problems

Hi,

I've been trying to play a Region 1 dvd on my laptop (the drive is set 
as region 2) but libdvdread is throwing up errors and so the keys can't 
be cracked. I know that the DVD will play if the drive is set to region 
1 (I've played it in this computer when the DVD drive was set to region 
1 - but its set to 2 now).

This seems to be the error mentioned as point 37 in the Ogle FAQ on 
http://www.dtek.chalmers.se/groups/dvd/faq.shtml

I get the following error when I try to run ogle:

If I try gxine then I get this:

I've trucated the output of both of those since it just repeats for each 
VOB.

Its a MATSHITA DVD-RAM UJ-820S on a Toshiba P25 running kernel 2.6.10

I can provide any other info if someone tells me what is needed.
