My experience is somewhat similar to nanocore's. Although my two 4-gb cards are nowhere near filled, I get skipping in the opening minute or so of every musical number I play, which ceases almost without exception afterwards for the rest of the musical number. (I use the term "musical number" as I'm principally playing individual movements to classical compositions.) Also, as I've earlier reported (and queried) in this thread, I can't seem to get to hear the opening bars of any musical number when initiating play using my Bluetooth headphones.
