Progressive or Interlaced?

[Chappy81]

I have an avi file that the AVICodec tells me is 25fps. But how do I know if this is progressive or interlaced?? I can't seem to find it anywhere on the codec. Is there another program I need to use to find this information?

Check tis guide: http://www.lukesvideo.com
Look at the section "Classifying High-Res".
It describes how to find out if it's interlaced and in which way.

Thanks so much, I'll give it a try.
