I'm very disappointed in Cyberlink PowerDVD 12 ULTRA, lots of issues and really slows down computer shutdown. I purchased in Jan 2013, but did not install upgrade until yesterday. I have been a Cyberlink fan since Version 7, and my Dell computer came with version 9 (9.5), both ULTRA Stable packages.

I installed Version 12 Update and it wouldn't start, then I read about a Microsoft Update in February that caused error 101 corrupted files. So after uninstall, downloaded 9.5 from my Dell Library, reinstall 9.5, then reinstall 12, I installed Patch below:

Updates PowerDVD 12 to build 2625

I did not install any of the previous patches. Am I correct to assume the latest Patch includes all the previous patches?

I'm having lots of freeze issues, PowerDVD Remote does not work and DLNA iPhone cannot play media files. I have read many posts that several of these issues were resolved by patches, hence do we nee to install each patch or just the latest (A note on the page would be helpful to disclaim Patches are mutually exclusive or the latest patch rolls up all the previous build patches).

I have sent Tech Support request for assistance (i.e. PowerDVD12.exe does not shut down preventing me to restart).

I will post other issues I'm having after I hear from Tech Support (i.e. Remote Control from iPhone does not see server & I read the knowledgebase article which was no help).
