Thanks for the quick response.
I forgot to mention my FCP timeline is 23.98 (hpx170 and canon 5d). I exported AIFF 2 track as it was only for dialog cleaning and not deep enough for OMF. Would that affect it adversely? Otherwise I made sure the PT session was at 23.98 (not 24/film) and went to work.
So frustrating. I will try a OMF export but read somewhere it might be a FCP bug where it interprets the AIFF as NDF or something. Arg.
