I thought AnyDVDHD was handling this in the past. But suddenly (don't know since when exactly) I keep having problems changing between Regions A and B. Of course there is this little Registry shortcut (c.f. http://forum.slysoft.com/misc.php?do=showattachments&t=6403) which solves the problem, but it should not be necessary with AnyDVDHD? Am I doing something wrong? PowerDVD 7.3 patch 3104 (as 3319 makes all sort of problems) under XP Home with a PIoneer BDC 202 BR drive. Thanks in advance for any hints.
