I answered my own question by sifting through aspect ratio posts and found "ReStream", a free utility that changes the flag of the MPEG2 file. It worked great!
This from Bob Cole:
Mpeg movie footage carries a "flag" which sets the aspect ratio. This flag may be observed and reset with freeware such as ReStream, available from the second site listed at http://www.videohelp.com/tools?tool=Restream
