I installed Rockbox on my 2nd Gen iPod Nano this evening, and all was fine and good (really, pretty awesome) until I tested out the Mpeg viewer. I hit play, the screen went black (but still glowing, clearly on), and it froze. I've tried pressing buttons, holding down buttons for several seconds, turning 'hold' on and off, even plugging the Nano into the computer (the computer won't detect it), but it absolutely won't respond to anything. There's no sound and the screen stays black.
Is there anything I'm missing? Something to be done other than leaving it sit for a few days until the battery dies completely? Any idea what caused this or how to avoid it in the future?
Update: Turns out the video conversion I used was the problem; I used one of the WinFF as recommended on the wiki and it works like magic.
