Question: Will this remote replace an Apple TV remote? How about an HDMI switcher remote?
Document: As long as you are comfortable navigating the online remote set up, this remote works wonders for a multi-component living room. I have it hooked up to my TV, my HDMI switcher, my DVD recorder, my DVD player/sound system and my Cable DVR. It does need to be recharged about once every week or two and needs to remain pointed at all the components for a second or two when starting or stopping an activity, but having only one remote is definitely worth it.
This is my first univeral remote. I like that I can program it to turn on multiple items at one time (TV, receiver, HDMI switcher, HD-DVD player). Sometimes though, it doesn't always turn them all at the right time and things get thrown off.I sometimes still use my original remotes, but this one has definitely made the turning on and off much more straight forward. Of course, it can't control my PS3, but I knew that going in.
Unlike every other "universal remote" I've ever bought, this one is truly universal. I've always had to keep original remotes handy for the functions that you can never get to work on other "universal remotes". With the Harmony 880 I really can put all my other remotes away for good!This is truly an amazing remote control! After the simple initial online setup I could have stopped right there, the remote worked great. It even controls my Octava HDMI A/V switcher.
I have never had to replace any rechargeable batteries and I wouldn't really know how to do this for these.Setup is very easy as long as you prepare a list of model numbers and which HDMI ports (or whatever) you are using in advance. Very good support for new devices. Devices which aren't listed, which are rare, you can still manually configure the remote... it's a pain but not that much of a pain.
This remote controls EVERYTHING and is super easy to program! Not only can you control your TV and DVD player, but you can also control your Xbox 360, non-standard appliances (iPod dock, Media Switcher, etc.) If you're looking for an IR remote that controls virtually everything AND is easy to use, this is your remote. It works with Mac or PC for programming. The docking station recharges the batteries so no need to get new batteries for this remote every few months.
This remote is a must for people with complex home theater setups. I have a Samsung Plasma TV, a Samsung Home Theater system, a Panasonic Blu Ray Player, a Comcast Set top Box and an Apple TV. It is seriously so easy to set this remote up. It guides you through a list of questions and drills down to your exact product.
I've had my remote for over a month now and have been very pleased with it. It was simple to setup and is easy to use. My wife was concerned that it would be too complicated when I bought it, but now she often talks about how easy it is to switch between components. The only aggravation I have had is that pushing the off button will not turn off my Apple TV. However, this an Apple TV issue rather than the remote just because of how Apple requires it to be shutdown.
This is a terrific remote. I have a widescreen tv, HD satellite service with DVR, an Apple TV, a 5 disc dvd player, a dvd burner, an AV receiver, and a 5 disc cd changer. Switching settings to get everything right was a major pain, and on several occasions, I had to write instructions for other people!
It only took one hour to setup the remote, I have a LCD TV, HD Receiver, Apple TV and a DVD player, you just connect the remote to your computer then the process is really easy, everybody in the house is able to use it, you basically program activities like Watch TV, or Apple TV, the activities feature is a great idea.
Questions like, "Does the TV have to be on COMP-1, HDMI-2, AV-1 to watch the DVD?" are in the past. The remote puts the TV in the right mode to do whatever activity you chose. Same with the receiver. Look for a sale or rebate if you have to, but don't hesitate buying this remote.
Answer: Apple TV yes. Not sure about HDMI switcher, it probably would because it has a learn function.
