Hi Tom, I've done some more testing, and was very surprised to find out that ffdshow seems to make no difference. I removed it from my system completely, rebooted and gameex will still show the videos, and still pauses for about 8 to 10 seconds every time. Also the mouse dissapears during that pause, and the system seems to lock. It's an ATI Radeon 9600, very generic card. Was bundled with Doom 3. My CPU is a pre SSE3 P4 though. Did you use anything SSE3 specific in the 9.71 build? Thanks for taking a look at this for me. I've tried as many video formats as possible with windows media player and the new ffdshow. No problems there at all. This seems to only crop up on the GameEx GUI.
