Hey all,

I'm designing an experiment in which in each trial there are two videos that is being shown together - one in every side of the screen . For some reason, the video in the left side of the screen flashes - it starts to play,flashes, and then continues. It happens in three different computers, but in the fourth computer it doesn't (all computers have windows XP and the same DirectRT version).

For some reason it happens only in the left side of the screen - it doesn't matter which video is shown in which side.

Thanks.
