Does anyone know the details on Playlists for SD? How many songs are supported, is SDXD supported, is there a max SD size, how many directory levels are supported, should the song path include a disk designator, like F:\?

Will the following .m3u example work:
music\artists\c\Coldplay - Viva La Vida.mp3
#EXTINF:176,Viva La Vida - Coldplay
