I can use media player fine for music and its ok for pics, but my videos aren't in the right format to show up in media player (they are .mp4) I tried using explorer, which worked fine on xp, but on home premium, (which is supposedly supported) it says that the device either stopped responding or was disconnected. I looked up firmware updates and could find none, and looked in the manual. Fortunately i was able to find a program called content transfer made by sony designed to allow me to drag them to a gadget and put them on. If anyone knows whats wrong please let me know.
