When I bought my home theater system 2 years ago, I was pumped about the idea of watching TV shows (Simpsons, X-Files, Fox NFL) in their surround sound glory. Well, I've been less than impressed with DPL. I was hoping by this point in time we'd be well on our way in the transition to digital TV, and DD5.1 for most channels. Well, since that's obviously not the case, I've been considering upgrading to a system with DPL2. Most of my viewing is stereo TV (networks and DirecTV). Is DPL2 the real deal? Is it worth upgrading to get it?
