David,
With Compressor, for stunning results from PAL>NTSC you have to use the optical flow technology in the frame control tab of Compressor. This will actually write the missing frames, and re-write the frames to the correct size. Pick the best settings and take a few days off (unless you can cluster some Macs) The results will compete with the best hardware converters.
