Development recently finished on decoders for two more formats, MP3 and AC-3. The MP3 decoder (ewmp3dec) will be added to the retail decoder package soon, and will be available as an update for people that purchased the decoder pack previously. We’re still working on the patent licensing for AC-3, so it won’t be part of the retail decoder pack just yet. However, both codecs are available to OEMs as a software license.
