You might need to get a high-end kind of solution to this. For example, http://www.mynevo.com/ has remotes that work with an extender kind of module the NevoConnect, which can route your IR to individual components.
This is done by IR repeater cables which go from a port on the back of the NevoConnect straight to the IR receiver on your target device, which means that the IR is not broadcast to both of your players. On the NevoConnect, you can use 6 of these to either send out IR or RS232 serial codes (some receivers, HDTVs and media servers take RS232 serial commands). But you have to use this with one of the Nevo remotes, which means that the total cost of this solution could cost just a little less than your two HD DVD players combined. On the other hand, you'll wind up with a remote control system that can also do home automation, like dimming your lights and closing the curtains, etc.
Some cables like this came with my HP desktop PC which has some tv-tuner and media center features.
There's a pretty good explanation at the Home Theater Blog about this kind of thing:
Maybe you can start there and find a less expensive way to get what you need.
If you could at least get one device to be powered totally off (and not on standby), then you might have a lower-tech way to get just one of the two players to respond to the remote.
