This is actually how I tested remotes before whether it be a tv or vcr or whatever.
If the batteries are dead or the intended target machine to control is not just reading it.
I would usually point the suspect remote towards my camphone (with camera function "on") and see if the light in front of the remote lights up when i press the remote 'coz by just using your naked eye, the IR on the LED won't be visible but by using the camera on your phone, you can see the IR light up.
For those of you who don't know this, you can try it if you have a camera phone or a P&S camera for that matter.
..in a DSLR, you have to take the photo to see it or if it has the liveview, you have to use that.
