Tested formats:
-.AVI Both Fraps and non-Fraps output - Both failed
-.WMV Powerdirector 10 output file and a few from the net - All but 4 failed.
-.MP4 Powerdirector 10, phone and net - All but 3 failed.
-.MKV Downloaded - Only 5/26 work (720p)
All files are at either 24/30fps with ranging bitrates 1mb/s to as high as 150mb/s. (Bitrate never use to be an issue, but if it is now... why are even those with less then 30mb/s not working?) Some videos with high bitrate work, others don't. Same with the lower end.
Audio? Stereo, mostly... though some are mono. Some work, some don't.
File size? Ranging from 3mb to 1gb. Again i have some random ones which work and others don't.
1.) I have the latest patch installed: 10.0.0.2231
2.) I have the latest graphics card Drivers from Intel
3.) I have more than enough space on my HDD
4.) I am logged in as Admin.
5.) I have Reinstalled Quicktime and PowerDirector and Codecs.
6.) I am using windows 8 and you guide on finding the logs is outdated.
7.) DxDiag: http://pastebin.com/87FbXjjX
8.) Can you convert the files? What need if all the normal file types don't work?
9.) Have you tried compatibility mode? Yes. No luck.
10.) Firewall? Comodo in game mode (Means it won't interfere)
11.) All these files can be opened and played in my video player and use to work in PD10.
Extra notes-
I use to be able to open all these file formats, but, without warning or any reason, now i can't. I haven't installed or updated any software which could effect Powerdirector, let alone anything else on my computer as there have been no updates. Though once this issue started i have tried to reinstall drivers and powerdirector etc...
Since which i have also re downloaded live movie maker and now, it works! (It didn't before, hence why i found PD10... (which was already installed on my computer but didn't know about) but now PD10 is broken it works... so there might be a link)
Just ask for more information if needed.
