I don't know that MPEG Streamclip has a codec that'll give you a square pixel - I always just convert my vid from rectangular to square pixels on final export from FCP. (I use the h.264 codec or sometimes the apple component video codec to clip in MPEG Streamclip, for the record).
But, say I've got 720x480 clips that I've made from 720x480 footage . . . I vid in FCP with 720x480 sequence settings (anamorphic 16:9) and then when I go to export from FCP I just export to 720x400 and it comes out fine. You do have to convert from rectangular to square pixels at SOME point, but I just do it on the final export and then don't have to worry about it.
