My TIVO QUAD will not hook up to a HDTV with HDMI. It worked for about 4 weeks, and then suddenly there is a problem. I am not sure of the cause. I get no signal from the HDMI port, and if I hook up through Composite ports at the same time I get a message telling me to unhook the HDMI plug.
I have rearranged and put the TIVO QUAD in a room with an older STDTV and hooked it up via component plugs, and put a TIVO PREVIEW in a room the HDTV and hooked that up via HDMI. But I would like to upgrade the STDTV. I would like to avoid sending the TIVO QUAD back to RCN cable company and losing all my recordings. I am thinking there is a setting wrong, but repeated calls to customer support have been unable to produce a guess as to the problem.
Also, can I determilne the manufacturing date of the TIVO QUAD. I am curious how long it has been circulating among cable customers.
