The scene of third-party multimedia players have been pretty stormy lately, which can clearly be seen if you look around in iOS forums with more advanced users. Dolby's forcing all developers to license their (widely used and essential) audio codecs at pretty huge licensing fees has resulted in a lot of players removing Dolby audio support altogether, (pretty understandably – we're speaking of quite a lot of money not possible to pay if you sell, say, under 20-30 000 copies of a, say, $2 app) not being able to pay the money Dolby have demanded.
