I have two ploblems.

First, I can swtich to fullscreen mode but the actual picture just switch to the smallest size in the upper left-hand corner, with the rest of the screen black (as it should be). What's wrong?

Second, when I play a specific .avi film it runs in slow-motion but the sound is ok. What's the solution?

does the slowmotion problem also exist if you use the windows media player. if yes the avi file may be incorrect. try to correct it wis virtualdub
