Hmm, that's a very strange error... "CyberLink Power2Go" is supposed to be
some DVD burning software?!?

I don't really see why this should interfere with your video, but from what
I'm reading on the Internet, it's because this software has a fake video
driver to allow capture of the screen while playing DirectX games?
You could try uninstalling CyberLink Power2Go from your computer, and see
if it works after?
We're working on a new version of the game that uses completely different
graphics code, and shouldn't have any problem (in particular, it will keep
your current screen resolution and DPI settings, but uses the video card to
stretch the image to full screen, instead of changing the screen
resolution).
I'll close as "cannot reproduce" here, but if you have more information,
feel free to add it to this bug report, thanks!
