Media Player Not Playing Files
 

I am currently playing mp3's using the built in media player. Every so often it will come up with the message unable to play media, if i restart the unit it works fine. Is there a media player available where this doesn't happen which includes tag support, is there a way round it.

ps I would rather play ogg files but that doesn't seem to possible from what I am aware - in case I get lucky does anyone know of anyway/program which will let me play ogg files and search through them using artist,album tags etc.
