Remember that by Directv nature, a mini is much delayed over the main DVR (which is also likely a Genie actually, in about 99% of installs), both audio and video. You would certainly not want to take the audio out of the DVR and route that thru any audio and expect the Genie Minis not to be WAY out of sync. The Minis simply dont sync audio/video with a Genie DVR very well at all. Looks like a best best is to use a Genie Mini audio out.
