I have tried installing AnyDVD with HD license key on my machine which dual boots. In one partition is Win Vista Ultimate 64-bit, and AnyDVD can't RIP an HD-DVD.. none that I have tried which are 5 different titles. It seems after I upgraded the AnyDVD to the latest version that my HD-DVD player software stopped functioning too. If I boot into my original 32-bit install of Windows XP on the same hardware, and most of the same software, then AnyDVD works like a champ and rips HD-DVD no trouble. The ripped version is then playable on my machine when booted with 64-bit Vista. The machine is a E6400 Intel Core Duo with Intel M/B, 2GBytes Dual Channel DDR, 3 SATA hard drives toatalling 1.25 TB, ATI Radeon X1600 with 512 MByte RAM. The HD-DVD is the XBOX 360 USB drive. I have Alcohol52, SlySoft software, CyberLink PowerDVD, Norton 2007 A/V, Adobe Reader 8, Adobe FLash Player 9, and WinRAR. What would you suggest trying to debug this further?
