[mythtv-users] nuvexport mpeg4 to mpeg2 but no video

I'm trying to convert recorded mpeg4 nuv files to mpeg2 using a DVD profile
so I can eventually burn these to DVDs. I'm using nuvexport, current as of
today and mythtv CVS current as of last week. Using nuvexport I select the
recording, then the export DVD mode, use all the default values and it
starts. It finishes the mp2 audio fine as that is the only thing in the file
at the end. I receive an .mpeg file without any video, or just the first
frame .. any ideas?
Also I notice down below in the output that it states: "INFO: profile type
is (PAL)" where can I change this, I don't want PAL, I need NTSC? could this
be causing my problems?
I've also using myth's built in transcoder on screen to transcode the
recording in hopes of fixing any capture problems with the same profile but
it hasn't helped this time around.
