PPT videos on a Dual Head System (Multiple monitors)

[Guest]

Help! Here at the Squadron we have a few classrooms and some systems that
are set up with multiple monitors. On these systems we are running dual head
video cards. The problem we have encountered is when we try to play some
PowerPoint presentations that have videos in them. On systems that only have
one monitor hooked up, they presentation plays fine. When you try to play
the presentation on a dual head (multiple monitor) system the videos play for
approx 20 seconds then lock up. I have tried putting all of the presentation
files on the local machine, the server and still have this problem. On a
system that has the dual monitors, the play time/file time says 21 seconds,
when the actual file is over 1 minute long. I have also tried swapping
monitor inputs to no avail. Any assistance woudl be appreciated!

Here is another item about the above problem. I have installed another video
card, so there are two in the system, one for each display. The presentation
disply still only shows about 20 seconds of video. If I swap the display
settings around, so that the video will show in the presentation view, it
will show the entire 1 minute 30 second video. I have tried using the Power
Show addin and that didnt' help any either. HELP HELP
