I have had my 3802 receiver for a few months now and have taken the time to program it (learn) other remotes. It works well (still saving for a Pronto or MX500), but I just noticed that when I turn the backlight function on I am not able to control any other components (DVD, TV, etc). Is this a common problem? Do I need to program the remote twice (once non-backlit and once backlit)? Thanks.
