I am having a problem when I open both programs of CyberLink PowerDVD 13 and WinDVD Pro 11 where they both go straight to a black screen. (Which rules out that its their own softwares fault) So I figured it has something to do with codecs because I have K-Lite Codec Pack installed. I installed CyberLink on a virtual machine I saw the screen, I then installed K-Lite on that virtual machine and I still saw the screen so everything was working fine.
I really cant find the root cause of this because Windows Media Player and my VLC still play videos and I can see their interface... I also have the latest video drivers as well.
