I have the same problem after uppgrading to quicktime 7.3, but only with clips imported with p2 log.
If I re-import a non working clips with final cut, it works very well. The soulution seems to be to re-import all files that where imported trough p2 log with Final cut instead.
What would a vise strategy be for reimporting files? Is it possible to batch import p2 files in finalcut pro?
I have hundreds of non working clips and hundreds of clip working clips? To manually re-import all non working clips would take a lot of time. Batch importing P2 files would really be a time saver!
