OMF export to Pro Tools

The omf audio export tool has worked for me over the years in SD, even if it’s pretty buggy. But it appears not to work from an HD timeline. I tried pasting the audio tracks to a SD timeline but this also fails. Yet an original SD timeline exports fine. Seems pretty crazy to me. Anyone got any ideas on this. What are others doing to get their tracks to a sound mixer.

Hi Floh, the two projects I'm working on originated on a tapeless HDXD camera, and were imported via the sony transfer tool. Neither projects audio will export to omf. Older disc based SDXD projects will export. I don't see why it would make a difference, but I've tried pasting a few of the newer audio clips to an SD timeline, and they won't export fro there either. The omf tool opens briefly, for about a second, then closes. I have occasionally struck problems before, and have managed to get around it by isolating the track with the problem, and moving the clips elsewhere. Like I say, it's pretty buggy. I've since worked out I can export an XML to FCP and export an omf from there. But it's pretty annoying that I have to use another product to perform such a basic function. Thanks for taking time to help.
