Hey Lee,
If you really wanna have some fun with your 15-1994, and make it so that you'll never need to buy another universal remote in your life (excpet to buy new 15-1994's when you eventually wear then out), build yourself a JP1 cable, and add device codes for any new devices that you might pick up, such as ReplayTV, Philips TiVo, Sony TiVo, etc, etc.
