Fixed it but..............

Everytime it has to load a new part of the video it lags the game for 1 second!

I am using your arcade lot and it lags soooo bad.

How can I stop the lag.

I got a good comp it shouldn't happen

Sometimes you may have other media players installed which are set to run when a video clip is played, so first you should do is check if you have any media players associated with your avi files other than the windows media player.

Another thing to check is for programs that may be running in the background and shutting them down.
