And out of idle curiosity, do you know if there's any difference between distort and "aspect ratio"?

There really isn't a difference - I think I used aspect ratio the first time I did it - but I like the mathematical exactictude of using pixel measurements (distort) vs. percentages (aspect ratio) because I'm a freak and 33.3333 etc. bugs me. *g* But since it rounds anyway, no, there's absolutely no difference AFAIK.

Thanks for the tip about creating a new sequence. I've never done that! Funky. I must admit, the G5 has spoiled me.
