If you are on a 64-bit OS and having trouble getting the PowerDVD 8 HD-DVD pack and MoovieLive tweak pack to be effective, it is probably because your registry structure is different. Here’s how to fix:
HD-DVD Pack:
Edit HDDVD64.reg and change all instances of “HKEY_LOCAL_MACHINE\SOFTWARE\Cyberlink” to “HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Cyberlink” and then run Install64.bat again.
Tweak Pack:
Edit Disable_MoovieLive.reg and do the same changes as for the HD-DVD Pack and then add the file to the registry. DO NOT change “HKEY_CURRENT_USER\Software\Cyberlink”.
