I don't know how I stumbled on to this website, but this
http://www.easyzapper.com offers a tivo enabled remote with a usb port
that shows your tv listings on an lcd on the remote. It has very few
buttons.
It claims it will simplify using all the stuff in your entertainment
cabinet like your dvd, tivo, vcr, etc.
The listings and member web page is free. No monthly charges (good
thing!)
It's called the "Harmony".
From the website:
For example, you do not need a separate button to choose between
controlling your TV or your VCR. With the Harmony, you say what you want
to do (e.g. Watch a Video) and the Harmony automatically controls your TV
and your VCR at the same time!
There are two buttons on the right hand side of your Harmony, the scroll
wheel button and the round button. To tell your Harmony what you want to
do, use the buttons on the right hand side to interact with the LCD
screen.
Pretty basic looking.

Inside your remote control.
If you are like most Americans, you probably pick up a TV remote control at least once or twice a day. Let's look inside and see how they work. Here is the remote we will be dissecting today:
The remote control's job is to wait for you to press a key, and then to translate that key-press into infrared (pronounced "infra-red") light signals that are received by the TV. When you take off the back cover of the control you can see that there is really just 1 part visible: a printed circuit board that contains the electronics and the battery contacts.
The components that you see here are typical for most remotes. You can see an integrated circuit (also known as a chip) labeled "TA11835". The chip is packaged in what is known as an 18 pin Dual Inline Package, or a DIP. To the right of the chip you can see a diode, a transistor (black, with three leads), a resonator (yellow), two resistors (green) and a capacitor (dark blue). Next to the battery contacts there is a resistor (green) and a capacitor (tan disk). In this circuit, the chip can detect when a key is pressed. It then translates the key into a sequence something like morse code, with a different sequence for each different key. The chip sends that signal out to the transistor to amplify the signal and make it stronger.
