I have the same situation with my xport and CD burner. A solution I thought of (but haven't tried) would be to get 4 pieces of polarizing film. Cut one to fit each remote, and put them in with their axes 90 degress apart. Install the film on each device over the sensor so its axis is parallel to that on the remote.
Polarized film has the characteristic that, when the axes are parallel or nearly so, they allow full light through, but when their axes are perpendicular they block it almost completely.
Once you've done this, one remote should not affect the other device (unless you use it sideways!)
