It looks like you're getting position3d data (49 bytes / packet) when
you should be getting position data (25 bytes / packet).  I'm not sure
why that is happening.  Just to check, remove the extra stuff in your
config file, to leave just one entry:

position (driver "rmpposition" canio "kvaser" max_xspeed 2000 max_yawspeed 80)

Can somebody who has Player 1.5 working with an RMP comment here?
Have you seen the problem?

One things regarding playerjoy: it's not smart enough to parse combined
command-line arguments.  So '-kvc' is not the same as '-k -v -c'.
