Definitely call Onkyo technical support. They can offer tech advice and assistance like giving you a DSP upgrade if you need it. If they can't help you fix it, they can arrange a replacement, since it's only been a few weeks. At least you can be confident that there are enough 906's in the country that a replacement unit will arrive quickly if you need to go that way. Call them first but make sure you have some time to wait on hold.
