When the voltage falls too low, the Rockbox button handling code thinks
that you have pressed the Off key. (The lower general voltage reduces
the voltage on the "off" i/o port to below the critical level.)
The lower general voltage can be because of higher internal resistance
in the batteries as they age, or maybe there is higher resistance
occurring elsewhere in the hardware. You could check this by trying
fresh, new, fully charged batteries.
The Archos Jukebox Recorder V1 was a great machine - I'm still using
