Jeff-
The 60i for slo-mo doesnt work quite as well with SD as it does with HD, simply because you're now talking about 240 lines, which is dreadfully low... so I wouldn't recommend it. For slo-mo, I use "smart" motion estimation in Shake. After Effects may also have something similar, though I'm not sure.
The video isn't released yet but I can give you a few stills. I've put them
here for a few days.
