What do you mean by heavily interaced? It's either interlaced, or it isn't.

Or it might appear to be interlaced on some frames but is in actual fact telecined with 3:2 pulldown, which is the more likely case.

BTW didn't you used to be JediTray?

OK, you're definitely correct about the telecining, as Virtualdub's Telecide filter takes care of it nicely. My only issue is that I need to get the frame offset correct for it to work. Does AviSynth have a better plugin available?
