I have Download/English version.

Yes, wmv files are played in WMP, but not in ActiveWindow Movie like in-game.

I tried install CCCP n K-Lite codec pack b4, but it's no use (btw, i'm using K-Lite now).I'm using latest ATI CCC n ATI Tray Tools, maybe that i tweaked around frown. Can u tell me what specific options in FFDshow or ATT/CCC that make video played in an overlay window like u said, i can try to enable or disable it.

Always have ESET running, should i disable it - but i don't think its doing any harm.

About manually setting the multic-core in the graphicoptions.xml file, i tried it but i keep revert the old value frown. And by deleting/rename the skill clips, they won't be played right?
