So the show I'm trying to convert is a download from a British TV broacast, so the framerate is PAL. Now this plays fine on the computer, but I wanted one for home viewing. So I opened up the handy-dandy FFmpegx sucker and tried to convert an avi to dvd. I changed the video size to 720X480. I changed the frame-rate to NTSC and I got this funky error from the log (in bright red with a clunk sound):

I suggest resizing to NTSC frame size, keeping NTSC film frame rate and setting a 3:2 pulldown, see if that overcomes the errors. -

ETA So I tried it again, with the NTSC rate (not the film rate) resized the image, no letterboxing and 3:2 pulldown set. It seems to be going.
