I'm upgrading to a new plasma and blu-ray but would like to avoid the expense of a new receiver, at least for a while. My current receiver is a Denon AVR-4800, which I am very happy with, except that it does not have any HDMI inputs. Is there any reason why I would not be able to run HDMI from the Blu-Ray and my Dish DVR directly to the panel and digital audio from both sources to the receiver? (I apologize if this question has been answered before, but reading similar threads just made me more unsure as the discussions often turned to whether or not such-and-such Blu-Ray player could internally decode the HD codecs, whatever that means).
