Hi Jerry,
and why not? Everything I would like to say is that isn't realy matter, where the media files are located. Indeed I was copied my media to another drive and after their reconnecting I saw this problem. Then I tryed to reconnect original project to original non copied media, but still with the same effect. As many people here, we are using Finalcut to offline cuting and we have to copy our mediafiles to our editors. We can't use media manager because the quantity of media files are realy big and when our editors finish editing, they can't again copy whole media to us. And btw why? We have it already, that isn't profesional workflow. And it is everything about reconnecting, because there is one way when the multiclips are all right in sync. When we name the source drive equal like destination drive, same path, the multiclips will not reconnected and they continued in sync. But this is NOT resolution. Sometimes FinalCut goes mad and some multiclip goes offline or out of sync automaticaly.
So If there is anybody from apple reading this forum, please try this and repair it please.
