Installing AnyDVD HD 18.104.22.168 stops PowerDVD 16 playing any Blu-ray disks. PowerDVD error says it cannot read a file on the disk. Ability to play Blu-rays only returns after uninstalling AnyDVD HD and rebooting. I am running 64 bit Windows 7 Ultimate. EDIT: I am using Microsoft Security Essentials (latest version) and MalwareBytes Premium 22.214.171.1243-1.0.160 EDIT: Same problem with 126.96.36.199. This series of buggered betas is rather freaking me out.
