Here is an idea:
Manufacture an IR emitting device that the consumer plugs in and sets on a table in the room. The device connects wirelessly or with Cat5 to the consumers in house network. The app then tells the emitter what IR signal to blast and when to start, stop, etc. the DVR. The app designer could then write an additional app to make the iPhone into a fully programmable IR remote control for the entire entertainment center.
