Thanks for reply,

I was intending to put the final file onto an SD card that they can view on the TV, and to view it straight of the laptop to a projector.

I don’t understand how the footage can play fine in a media player on my system, the audio sounds perfect in vegas as well its just the preview. I notice the lagging is even worse if I try a few crossfades and effects.
I have read a few forums that are saying to compress the files?

Thanks
