And I'd like to know why, and if it's possible to make it encode interlaced? Or am I the only one with this problem?

I use v.2.1.2.12 (the last version), and encode AVIs captured thru a standard firewire card from my DV-camera. PAL.

I can't find any settings about interlacing. Please help me. I can't use NVE before this issue is solved.
