I have a Roamio Pro and 2 Mini's. The Roamio Pro and one of the Mini's are in different rooms, but you can hear both tv's from each room. Is there not a way to get the Mini in perfect sync with the Roamio? For example, if you're watching the same show as the person in other room, you don't want to hear the slight echo. Or if you're having a super bowl party and want all Mini's to be in sync with the Roamio pro? I saw in another thread that people were recommending a hdmi over ethernet solution. However, it seems like it would be built into the Tivo software? Something like how Sonos automatically syncs sound with different amplifiers so you don't have an echoing effect.
