How do I check if the input is progressive or interlaced ? still images in mplayer don't show interlacing artifacts, does that mean that the input is progressive ? > The 'A' tag isn't right but that's usually not a problem because > 0:0 means unknown and most tools will use a (hopefully correct) > default.

That confuses me a lot. If I dump the mplayer output to a file and give that to yuvscaler I get no error.
