How can I set up my Slingbox M1 to interface with my Channel Master DVR+ CM-7500GB16? I'm suspecting I cannot without the HDMI connection on the M1. Any suggestions or converter cords/plugs, etc.? Any solutions available? The DVR+ does not have component and audio inputs/outputs, only HDMI. The Slingbox M1 was a gift, so no research was done prior regarding compatibility.
