[Avid-L2] Re: AMA relinking issues with MC 6.5

When I first used AMA, it was with v5 (or was it v4?) and all the original rushes (XDCam EX) had been duplicated on a second set of identical hard drives. We transcoded to DNx for the editing, and when it came to conform at the end, we couldn't link back to the XDCam. We then realised that it was because we were trying to relink to the backup drives and not the drives used to AMA in the first place (eventhough all duplicated drives had exactly the same names as the master drives).
AMA seemed to give the drive a unique identifier, and not only link a file based on its path on the drive (like FCP does). I seem to remember that Avid changed that later, in order to make AMA easier to use, and more reliable. Which would explain the problem you're having.
