Cannot render from original 1920x1080 MP4 movie file to 640x480 WMV movie file.

Vegas will always lock up and error out when rendering a 1920x1080 MP4 to a 640x480 WMV

I used to be able to do this before upgrading to the newest Vegas Build 216

I am able to render from original .mts files ( 1920x 1080 ) to 648x480 WMV format.

I am able to render from 1920x1080 MP4 to 1920x1080 WMV.
