well sorry I can't help, OMF never worked properly but I did a lot of work with that format, ( when exported it had to be v2 and have the crossfade box unchecked for importing into logic 6 and logic 7 anyway), but it sounds like your right, exporting issues... Logic 7 use to add a few samples on to the start of a bounce and I used to rock it in by ear if I was importing it back into a mix, I've noticed this again lately working with friend on 7.2.3? there is a couple on milli seconds at the start on his bounces but in Logic 8 if I export the same loop or seq it is spot on. Perhaps when working to video the problem remains, well at least with cues anyway, really for me this is the best version for working with video, but then again, I have never exported video with cues, I've always supplied aiff given min/sec when necessary. We work with FCP in the next room and everything is at 48khz. OMF is happily forgotten about weather that is part of your problem or not. Did you try posting this over at the apple discussion boards?
