Subject: Re: Brute force bug hunt

Yes it is similar to the silent play bug with version 1.4 however it
is a little different.

This only happens when it is on the car seat boucing around. Which I would
conclude that it is something that is "set off" by mechanical vibration.
It is different from the silent play bug that the screen goes blank, and the
song never returns, usually the silent play bug would start playing again
when the buffer was empty and was filled again. This is also when the
recorder is just playing the song (no ff/rw activity). The only way to
recover from this is to power down the unit. I however do not have
a solid red led, eventually the thing goes out.

If you guys can think of any experiments to do, I can or some debug code
to run I can run it when I get a chance (have to go some place in the car).
