Thanks for the response,

All my movie files (mpg, avi, wmv) play normally on my computer using windows media player or other software I've installed (editors). They just wont play when called in c-lite.

I still think something is blocking c-lite from accessing the libraries while the routine is being executed. Vista has a DEP (Data Execution Prevention) area which I've turned off while running c-lite, but that didn't help.

I've used 3dGS in the past (A4) and I REALLY want this to work. Thats why I'm being so persistant. Any other suggestions would be greatly appreciated.
