And then some do play. The only difference I see is those that do not play are commercial CDs, while those that do are user created. Additionally, those that are ripped by Mezzmo and do not play, WILL play fine if ripped and served by Windows Media Player. The Media Player files show on the tv as MP3 like the Mezzmo files that do play, while the Mezzmo files that don't play show on the tv as LPCM. Is there a fix for this?
