The UTV remote has an "auxillary" button. If you can't find published codes, you could find them manually. It may take a while because there are several hundred codes. You might also contact the manufacturer of your A/V receiver to see if they can tell you the code for your remote.
BTW, I hope this is not a deal breaker. The UTV is so fantastic, it would be worth it, even if you had to use a separate remote for your A/V receiver.
