Here's my situation: I just purchased a 2013 Samsung Smart TV (Model UN55F7500) and Tivo Premiere. According to everyone I've spoken with (the Best Buy Geek Squad that installed everything, Samsung technical support, and Tivo technical support), the two devices can't communicate with each other when it comes to changing the channel. I have a cable card installed in my Tivo, which means Tivo is acting as my set-top box and has control over what channel is displayed. So, when I change the channel on the Samsung TV using the Samsung remote control, nothing happens. This not only prevents simple channel switching using the TV remote, it renders many of the TV's "Smart" features useless. For example, the main Smart TV page shows channels, programs and recommendations that are currently showing -- but if you see something you like, on say, HBO, and click that window, nothing happens because the TV tries to switch to that channel but it cannot. The only way to change the channel is by using the Tivo remote. Here are the possible solutions I've explored: 1. Use the Samsung IR Blaster. The Samsung TV comes with an IR blaster that is designed to enable the Samsung remote to serve as a universal remote. Hence, you plug a cable to the back of the TV and place a transmitter in front of the set-top box. In talking to Samsung, this is the set-up one is supposed to follow when operating the TV with a set-top box. However, the Samsung technical support person I spoke to told me that the Samsung IR blaster (at least on my model) is NOT compatible with Tivo machines; it is only compatible with the manufactured DVR machines in use by the cable companies. Multiple attempts to get the two devices to link confirm this. For what it's worth, the HDMI connections seem to be working just fine because I can change the channel using the Tivo remote, and view/play Tivo on the TV just fine. 2. Use Tivo as the "universal" remote. My next attempt was to see if I could use the Tivo remote to control the TV, and the channels along with it. This doesn't work because the Samsung Remote is a touchpad and the Smart TV screen it interacts with essentially looks like giant smart phone screen (meaning you swipe across the touchpad and click things as you would on an iPhone). The Tivo remote (with its basic arrow buttons) simply can't interface with this technology. In other words, it can't navigate through the TV's menus and Smart features because it lacks the interface to do so. 3. Use a third party universal remote (e.g., Logitech Harmony). In theory, a device like this will talk to your individual devices, but it still cannot make them talk to each other. Therefore, I'm still back at square one if I use the Harmony remote to click on "HBO" in the Smart TV menu, because the Smart TV still needs to send a command to switch to that channel and it has no way of telling the Tivo to do so. I'm at my wit's end in trying to figure this out and none of the technical support specialists I've spoken to have been able to offer a solution. Still, it seems inconceivable to me that these two major brands can't operate together. Has anyone experienced this issue or come across a solution? Any wisdom/advice/ideas would be much appreciated.
