OK, I really don't have much experience with the MB (read: I have one but
have never gotten around to programming it) but I think that you could 
be experiencing some sort of noise problem.  Try running the motors off a
separate power supply and have some sort of isolator between the miniboard
and the motors.  An isolator can be some sort of transistor setup where all
you use the motor ports for is to 'flip a switch'.  You could use relays
possibly but I suspect that they would generate just as much noise as the
motors (or close to it).

Have fun and remember, I may be totally wrong but it's worth a shot right?
Chuck, Fred, anyone care to comment on my guess here?  Even Steve if you
want :).

Bye,
Ray
