mp4 video to AMV 160x120

[Robert Moskowitz]

I am getting back to this.  To my disgust, the Trio Win utility does not 
support mp4 as a video input format!  So much for truth in advertising.  
So now to ffmpeg built for amv output support...

I have not done a rpmbuild for years.  So I need a bit of a tutorial

I hope, please.
