Why do videos play fullscreen through projector when sized on slid

[Guocera]

I am importing mpeg videos to training slides and sizing them to certain
sizes so text can be placed next to video, works fine on lap top but when
plug into projector, the video goes to full screen. I have not asked them to
automatically blow to full screen. It used to work but not anymore, I think
it could be because I have updated to WMP11? Not sure, any ideas out there,
p.s. its also happening to other trainers laptops here not just mine?
Thanks

Most likely a function of your graphics card with a feature called 'theater
mode.' Here is a quick info tutorial on the topic:

Thanks Troy@TLC
Absolutely fantastic, found that you have to have to projectors plugged in
to make efects, but apart from that, nice one from VTECH South Australia.
