actually whay happen is that resolume opens up the relocate dialog where you can browes your folders for the media, but actually, limitis what you are seeing, e.g files and folders, to the name of the missing clip. now here's the problem: even if the clip exist in the folder your looking at, still you can see it! HAAA???
now, if you go to the file name field in the bottom of the window and press in *.* ---> Enter, Ah AHH! it works...all of a sudden you see every file that's in that folder, and then you press on the one you're looking for and then the whole relocation thing works, even for other files in that directory...but it should not work that way...
