Does it make a difference if you edit at 23.976p or 29.97i? I've always just assumed the editing should be with progressive frames whenever you can.
23.976p is best. Your work can suffer from blending problems if you don't.
It's always better to remove the pulldown flags, then edit. After all, it's easy enough to put them back afterwards with dgpulldown, so why risk problems? :-)
