I have a Dish-network PVR. The remote is great for watching TV but not for my Home Theater Setup. The PVR Remote is RF (nice since my gear is in a closet) and is laid out very nicely with all the PVR buttons arranged nicely. Is anyone using an universal remote? And if so what one? How do you have it set up to deal with your PVR buttons? Anyone using the MX-500?
