WInDVD Platinum + Region Free Hardware=problem...?

[jakobkraft]

I have WinDVD Platinum, was using it for a while on my liteon 163, which has region protection. I recently got hold of a Toshiba dvd-rom that did not have any region protection and now when I try to play a DVD in WInDVD platinum I keep getting a region confirmation window, asking me over and over if I would like to keep this region. If I answer yes, it just keeps popping back up.
I downloaded demos of PowerDVD and an older version of WinDVD 3 that came with my videocard, and they work fine. I remember vaguely reading about an issue like this concerning windvd platinum in some forum a while back, but can't remember which one.
Basically, has anyone encountered this issue, and if so, is there a fix? Thanks...!
