Audio and video drivers are upto date. Latest version of media player. It loads in previous versions of PD that I still have on my computer so its not my machine that is the problem. After several uninstalls and re-installs trying to sort out other problems that PD presented it still does not like WMV. I had a similar problem with MP4 files with it but after doing yet another un-install and reinstall to sort out Magic Music, or whatever they call it now, it now works/loads MP4's no problem.
No I dont have any Virus or malware on computer. Iorbit, AVG, Malwarbytes, and a few others on my machine have been run several times to check.
I just accept that Power Director in all its forms is very buggy. My latest non working bit is burning discs, ever so problematic. However I have Cyberlink Blue Ray Disc Suite installed and I burn them through that. So its not lack of knowledge or my computer that is the problem.
Every time a new version of Power Director comes out I get it in the hope that the latest version will have the bugs finally ironed out, each time I am disappointed. Sadly the next time I buy video software it wont be Cyberlink. Such a shame as I actually like using the software (when it works) so no update to 12 for me, I am currently running 11. Adobe you have a future new customer.
