Good to see that you are investigating the issue.
There are many ways to check the changes with free 3rd party software, so don't even go there. Just don't.
The ticket I opened with CyberLink was, as I expected, kind of useless. It could as well have been a automated answer.
"Thank you for contacting us. Update your drivers. Make a DxDiag and send to us, Send us your serial. Send us a screenshot with the error."
Not a chance. You already know of this problem, if not - just google it.
