I'm using a Verbatim 8GB SDHC Card. Have placed mp3 files on the card in an "mp3" folder - no other folders on the card. Unfortunately while the music appears on the card (when viewed by computer) only a portion of them are visible and accessible using the TT Jukebox. Music placed in the folder using TT Home and attempted. Also tried copying direct to the card in Windows XP. Suggestions?
