ahh ok. most people are interested in
anydvd's copy protection removal capabilities which was why I was a little lost.
I believe anydvd should remain set to region 1 regardless of what region you are in. (I read this in an earlier thread...I can search for it if you're really interested in why)
aside from that, there are no settings to tweak in anydvd.
the dvd should play as normal.
try opening the disc from within wmp...
I'm not familiar with playing discs from other regions, but anydvd should take care of region problems.
maybe some more knowledgeable can chime in, but you may have a PAL vs. NTSC problem. I'm not even sure if that's possible on a computer though. are the discs you're having trouble with ones that you've played successfully before or are they new issues?
