I'm sorry, I have to dig this up again...but I couldn't find the location for those files in the linuxmcetag.
I think however, that the issue is a bit bigger than that:
If I copy new video files on the the drive, said files will not be added to the database automatically, not after an hour, a day or a week. If I go to the directory containing those files, I can click resynchronise...and the files will be added.
Tagging is another issue...lets say I have a whole season of a tv-show and want to tag it- first I need to resync the the directory, then I try autotag, which gives me an error and after that one random file will be tagged. After that I try to tag each file manually, which also gives me an error- Series ID::259063Duplicate entry '7997-0-0-0' for key 'PRIMARY'- for example, but at least that episode will be tagged after that.
So what can I do about that?
