2nd Aftermarket DVD player (A or B IR channel)
 

When I purchased my 2012 Chrysler Town & Country last year I had a dealer recommended installer install a 2nd aftermarket DVD player in the van. Unfortunately we've found the built in (single) DVD player broadcasts on both IR A and B channel. This interferes with the signal for the 2nd DVD player. Is there a way to force the factory install DVD player to use only channel A or B?
