Advertisements I have a Series 6, running into a Denon 3700, then out to a 4k HDBaseT extender to a Samsung 4k TV.... just installed. previously i had a older HD TV and a Marantz over same extender. Running all streaming apps worked fine... whether the receiver was on or off (passthrough). Now i can watch live TV fine, but all the streaming apps give me an error. Bypassed the Receiver and get the same problem, as well as when trying a brand new Cat6 cable. Have also tried another extender that used to work on the older setup. So my guess is this has something to do with the Tivo box and the Samsung. Unfortunately, i currently have no way of testing with an HDMI cable (unless i buy a 40' to test). Any thoughts GREATLY APPRECIATED.
