I could definantly see this happening. the computer receives the 'play' 
button from a dvd remote, issues commands to control the audio system, dim 
lights, and then sends the 'play' button to the DVD player inside a 
cabinet where it can't see the remote directly.

but in any case, it shouldn't be hard to share a table of mappings.
