I'm trying out AnyDVD 22.214.171.124 with a Plextor Premium drive in an ADS Technologies Dual-Link 1394/USB2 drive kit (I know I could've bought a drive like this already but it was cheaper to do myself and after the fact i bought an internal). When playing an audio cd, AnyDVD frequently BSOD's in XP Pro - ANYDVD.SYS crashes. :a I've tried the Plextools Pro audio CD player and Windows Media Player 9. Seems theres a bug with external drives. I'll check to see if the Audio CD Protection option is the cause. It never used to do this with 126.96.36.199 albeit I don't think 188.8.131.52 had Audio CD protection removal.
Have you tried the safe mode option in AnyDVD?
