If you can rewire the outlet to switch at the dimmer location, this will be your best solution. Otherwise you can use a switched outlet device such as the Niles APC2 or AC3. The downside to this solution is it will cost more for the equipment and it will not give the level of automation you can achieve with the Lutron.

Whatever you do, DO NOT plug the light into a switched outlet on your receiverthis will result in noise and picture problems.
