The .new is not an issue but it does tell me that the sources are being tracked by the shorter 8 character name. You will see that in a column called “Tape”.
That being the case, you won’t be able to relink regardless of AMA or not. I would suggest that you download an application called “MetaCheater” do a google search and you will find it. This will create an ALE that extracts the REEL ID to which you can merge into your AMA clips. Or you may have access to the original ALE from the camera. Either way, that info needs to be merged into the AMA’d clips to have the 8 character file name tracked. From there, you will most likely need MC v6.5 to allow relinking to an alternate column.
