So, I had K-Lite codec pack already installed on this PC before I installed PMS.
Everything was working fine on my PS3 - but when i wanted to launch Media player classic/BSPlayer/any other video app, and drag it to the second monitor I use,
Which is an old CRT, it would make the app HANG has soon as the video attempted to display on the CRT.
I tried uninstalling K-Lite codec pack as I thought i had ffdshow conflicts - didn't work.
Next im going to try and uninstall PMS and just use the codec pack to see if PMS is the culprit.
Any other advice?
