Sorry, it wouldn't let me ask more questions directly, so starting a new discussion.
Original question: I have a base 4-tuner Tivo Roamio and I would like to connect an M1. If I use one of the Gung-Hu HDMI splitters, can I connect the M1 and also passthrough my HMDI signal to the existing HDMI connection to my A/V receiver?
Original answer: Use a 500.
So, are you saying that using the Gang-Hu splitter, my original configuration scenario would not work? What would not work? The HDMI signal would pass on thru to my A/V receiver, correct? And the HDMI would be converted and passed on to the M1, correct?
