Heat sources near the player can be the culprit (infrared light is basically heat). Plasma TVs emit a lot of infrared, and 3D TVs that use infrared emitters to sync up their 3D glasses can also be a problem. Sometimes repositioning the player deeper into a shelf will shield it better.
To see if this is the problem, try unplugging all the other possible sources of infrared and see if the player is more responsive -- judged by front panel displays, say when using the Resolution button.
Also make sure that both batteries in the remote are inserted the correct way around.

Just to add to the other replies, I recently had an experience that was very surprising.
I had heard of others say it could cause problems with your gear, but I always thought it was rubbish.
I am referring to fluorescent lighting.
I have used fluorescent bulbs quite a bit and never had issues before, but when I put 4 large fluorescent bulbs
in the ceiling lights of my living room, we had serious issues with the remotes not working when the lights were on.
Once I took the bulbs out or turned the lights off, the problem disappeared.
