New feature: easy codec installation, please test

Testing this with MP3 worked, although I had the option of two different 
  packages dealing with MP3, which might confuse users.

However, clicking an ASF only opens Totem, but does not play the file 
nor try to install any codecs, nor present an error message. Again, this 
might confuse users (like me). I must say that I did not manage to play 
this file under Dapper, which is why I was hoping for the new 
auto-detection.

Anyway, great feature! But it should be disabled for ordinary users.

Regards,

Andreas
