Thanks Steve. This is a great help. The mencoder manual has a lot
of good information on how to determine interlaced vs progressive and
tecline. I will need to figure out a way to deal with mixed
material. A good example is one of the Star Wars movies that were on
Cinemax recently which switches between 30000/1001 fps NTSC and
24000/1001 fps progressive.
