How to choose an IR receiver?
All IR receivers (that I am aware of anyway) just output a digital stream (all they do is demodulate the carrier frequency and correct for ambient light) - it's up to whatever is connected to the reciever to decode the information. This could be a microcontroller, or a dedicated decoding IC. So you (probably) have right receiver, you just need something suitable to connect to it.
Make sure it uses the same modulation frequency as your remote, although if you are getting output when you press a button then it's probably correct (usually 38kHz, 40kHZ, or similar)  

There are various standards used, but the Philips RC5 or RC6 is probably the most common. See this site for information on all the different IR protocols.

There are plenty of tutorials and code out there for setting e.g. a PIC or AVR up to decode IR (I have a simple project here based on a PIC16 I used to control a Sky box ages ago, but this is the other way round to what you are trying to do - if you need to control whatever the remote did, you will either need to find the codes for your remote also, for example I needed the List of Sky Remote Codes, or read the codes into your firmware)
