Sorry, if you said that before, I mised it. Too much context switching.

If that is the case, then you are probably right. The problem is in the corrupt installation, not the tracker database. Sorry, I cannot help much. Stock media player is one of the applications I tried and chucked away almost instantly. I did not like the stupid design. Have you tried uninstalling and reinstalling?

I use Filetug as my media player. Much better as it can play by a physical directory structure rather than tags. It works fine in Aurajoki.
