I have Vista x64 running AnyDVD 18.104.22.168. I can rip regular DVDs all day long without issue. However when ripping BluRay disks, the first rips perfect and completes. But, simply INSERTING the second Bluray causes AnyDVD HD to hang. I cant even shutdown the system. The only thing I can do is power off hard (then the raid system takes 6 hours to verify the system after an unclean shutdown). I have tried numerous titles and so far it doesnt seem like it matters which BluRay disk I try. Its always the second try. BTW: Im ripping using the built-in AnyDVD rip option in the system tray.
