I've used the color correction menu to crank up the green saturation for green screen in conjunction with "Filmlike" gamma settings, and not suffered any ill effects for it in post. But as always, test for yourself to see what settings look right to you.
"Zero" detail level in PAINT>ROP>MASTER DETAIL is nominal level; negative values reduce detail enhancement even more. You can also make the detail ehnancement outline line "thinner" by increasing the value of the H. DETAIL FREQ in the low/mid/hi settings. There's no rule that says you have to avoid detail enahncement when shooting greenscreen, and in fact standard def usually benefits from a little detail. But again, what you see on a properly tuned monitor (which means tuning the "aperture" level in the middle) is what you get.
Oh, and be sure to record in DVCPRO 50 mode for the best quality comp.

So one work-around is to shoot/create both elements at 30P so all frames match, and you often don't notice the subtle difference between 30P and 24p. Another route is to shoot both elements in 24P"A" and remove the pulldown, composite in true 24P, and convert it to 60i later.
Edit: All that said, people have been compositing telecined film elements with a 3:2 pulldown for years, so it's not necessarily the end of the world if you do it that way.

Thanks for your suggestions. I appreciate the help. Good idea about the H frequency detail. I'll look at that.
