Hi Steve,
This worked – problem solved – thank you so much……. I think i understand the issue now too.
I dont think there was a missing file, just too many files for vegas to cope with in the project. I have moved over to card based filming and was dropping all the media files into the project (100’s). Now in the ceremony for example, removing the unused media took eveything out except 4 files.
Thank you one again.
Kind regards
Martin
