I have my DirecTV HD receiver connected to my HDTV via the HDMI connection. I now want the audio to go through my AV receiver but also want to keep the digital quality in the picture. Can I still keep the HDMI (even though it carries both audio and video) connection and run a different audio connection through the surround sound system? The other way would be component connections from the DirecTV receiver into the AV receiver then out from there into the TV component connections. Thanks.
