I have spotted a new other problems, should I report them all on trac?

- Quit method should be in root object, not the Player object
- Sending play message when playing should rewind, it currently  
crashes VLC's control subsystem.
- /TrackList/GetMetadata is supposed to number tracks from 0, VLC is  
currently numbering them from 1. Indeed if you request metadata for  
track 0, it crashes VLC.
- /Player/GetStatus is returning large integer numbers for looping and  
random status.

flophtaf:trunk njh$ ./examples/status_test.rb

I am thinking of writing a test suite in Ruby to check a Media Player  
for  MPRIS v1.0 compliance, good idea?

Cool thanks. I have listed these on mpris.org.

Another request for version 1.1 of the specification is listing the  
standard key names for the metadata dictionaries.  The ones I am  
seeing from VLC are:

{"status"=>1,
  "artist"=>"Mistys Big Adventure",
  "URI"=>"/Users/njh/Music/fashion_parade.mp3",
  "title"=>"Fashion Parade - Instrumental",
  "date"=>"0",
  "length"=>222187,
  "description"=>"                            ",
  "genre"=>"<Unknown>",
  "album"=>"Fashion Parade",
  "tracknum"=>"5"}

What is the 'status' key?
