I have a Mk.2 (not 2a), dual-drive, formerly running 1.03 with no trouble.
Every time I've tried to install *any* version of 2.0 on the device I've had the same problem: the install goes fine, everything's working great, I can use the player fine with the buttons/knob, but as soon as I hit any button on the remote except for the volume adjuster, the player freezes -- and then, on subsequent boots, hangs with "Starting audio..." on the display and, from the serial port output, obviously just after running "player.cpp".

With the player like this, emplode won't even talk to it on serial, ethernet, nor USB. I can get a shell by hitting control-C on the serial port, but I'm at a loss as to what to do to fix this.

Downgrading to 1.03 fixes things -- of course, upgrading to 2.0bX breaks them again.

Does anyone have any idea what might be going on?
