How to know whether video is progressive or interlaced?

[BaRtMoN]

Hi.

I've read some of the basic articles and guides on the mainpage but i haven't found the answer to my question even when searching on the forum. I have some Xvid/DivX encoded material, which I want to encode to MPEG-2 (with CCE) so I can burn a DVD Video dics.

How can I find this out? Thanks!

if you have mpeg4 content (xvid/divx) it's most likely progressive... if you want to test it nonetheless, create a simple avisynth script with just this one line
avisource("X:\yourdir\youravifile.avi")
and play it with your favourite player, forward to a scene which contains a lot of motion and look for interlacing artefacts (those horizonzal lines) if you encounter any, you are dealing with interlaced material.
