I have two questions: the first concerning progressive and interlaced video. I am attempting to convert an mpeg-1 file into mpeg-2; however, when I use mediapipe's interface and follow all the appropriate steps, I can't seem to get the video to stay interlaced. It does 0.02% and then says forced progressive video.. any solutions?

My second question is this: what is the best DVD creation and conversion software for Mac? All suggestions would be greatly appreciated. Thanks!
