That player wants the IR emitter in a very specific spot and it's nearly impossible to see through the front. I fought with this for some time and eventually found it by holding the emitter a foot away while holding a button on the remote, zero in on the exact right spot. Has worked perfectly ever since. I would definitely recommend silicone or hot glue to stick it on permanently because it doesn't take much to mess it up. Use emitter only, turn iR blaster off, and set to RF only.

Also on that player, in order to get pause to work you are going to have to update it's firmware and learn the pause button from the factory remote to URC.
