Wild West - Series 1 (region 2) problem
 

I've been using my Toshiba SD 4900 for multiple regions. I have probably about 30 R2 discs, and I've never had a problem with any of them until recently. I just received " Wild West - Series 1" from the UK and the disc won't even load on my player. I've tested it on a friend's player as well (also a Toshiba 4900) and it doesn't load up on his player either. I was wondering if there were any known problems with this disc? Or maybe if theres some incompatibility with the Toshiba? Any help would be appreciated...
