I'm running my GTV to three other tvs. I have a 2 ft HDMI from Charter box to GTV. 2 ft HDMI from GTV to splitter. Then: 50ft hdmi to bedroom 25ft hdmi to den 50ft hdmi to home theater Here's the thing, it works. But its finicky (ms?). Hit power and nothing happens. Turn on/off again, and it works. It's strange and I wonder if this is a splitter box issue. Anyway, I would suggest don't do this unless you want to use the ethernet thing but I have not found enough information on that yet. Like does it carry sound? In all formats? When it works, its really cool, except I have to reprogram the remote to each room's tv. But I might try to obtain a second remote for this unit, or a third if the second works. Anyway don't laugh at me haha I'm trying to consolidate.
