The reason I originally included my mencoder recipe was that I had hoped it could provide clues for finding an ffmpeg equivalent that deals as favorably with pullup for as many different types of input. My mencoder method's only real deficiency (other than being dependent on deprecated software) is that I always get underruns if I try to copy audio rather than encode. The ffmpeg method I had already developed works pretty well, with the apparent exception of certain 4x3 DVD titles such as the one for which I provided the excerpt.
