Hi Justin,
3.2 upgrade had no effect. I tried your suggestion with moving & undoing but again no result – none of the clips (including audio files) are linked. Timeline structure is in tact and manually you can re-build but nothing seems to have worked. Extremely frustrating. Occasionally some of my sub-chapters will have some files linked but perhaps < 10%. Please let me know if you stumble across any further suggestions. Although I've used Premier for a decade, I'm not an industry professional - just a Veterinarian producing a major DVD on Breeding management
thanks again
john
