Marantz sr 5005 setup question

Hi folks, just bought a Marantz SR 5005 to replace my Harman Kardon AVR 254. With the HK I enjoyed watching DirectTV while listening to music on my Wadia ipod dock. So, I was able to watch hdmi video from the Directv reciever and listen to digital coax audio coming from the Wadia. I setup the AUX input on the HK to play hdmi video and digital coax audio very easily. With the Marantz I haven't figured out how to do this? Can anyone tell me what I'm doing wrong? Is this even possible with the Marantz? Any help would be much appreciated!
You can, you'll need to set up a new source with HDMI for video and coax for audio it can easily be done in the input settings.
Thanks Kennyt, each time I try to setup the source labeled TV with the HDMI from the Directv receiver as well as coax from Wadia, here is what happens. The hdmi input from Directv receiver is then removed from the original source labeled SAT in the input assign menu and moved to the source labeled TV. When I select the source labeled TV on the input selector, I have hdmi video and audio playing and no audio from digtal coax. But, the digital coax is showing up in the input assign menu as being assigned for use in the same source. Make sense? Any ideas?
Set the digital input to coax, I think that is all you need to do tho it's been a few months since I went through the setup, I think you can do it though.
