Hi, just tried MediaBox and am very impressed. However I noticed 2 things: 1. As noted before on this thread the FM Radio remains on. This leaves the chipset powered up and drains the battery. I didn't notice initially as I had not plugged the headphones in, so I guess it boosts the power to try and get a signal. My fully-charged battery ran flat in just 10 hours with the device in off-line/locked mode. 2. I started some videos from my camera - these played fine, but the mplayer instance remained and responded to the play/next/prev buttons, playing over the songs I was actually trying to listen to (both video and audio!).
