I am using video files, mpeg2, from a Lumix FT1 camera in 720P. When I create a movie in WLMM and output as a 720P, or any other size output, I always get a black border on my widescreen laptop monitor or through my media player to my plasma TV.

Note the input videos play full screen on laptop with VLC or Media Player and on the media player on plasma TV.

How do I eliminate the black border so my movie is full screen?
