Will ATVFlash play Multiplexed MPEG - 1/2 movie files

After exporting several movie files off of my Sony HD camcorder, I noticed these .MPG files show in my iMac finder as Multiplexed MPEG - 1/2 files.

I can only watch them using the VLC player - Quicktime won’t play them

Now I noticed there is a VLC application that you can download in ATVFlash - I did this download, but how do I tell ATVFlash to play these .MPG files using the VLC player?
