I'm new to DirecTV, having subscribed in early November--loving the service, but wondering if others are having trouble with general full-screen and mini-Guide slowness. For 5-6 days Guide scrolling is fairly crisp but degenerates rather quickly after that. Symptoms include very sluggish response in both full-screen and Mini-Guide modes, and while in Mini-Guide mode, if I attempt to scroll thru multiple channels the response is not only very slow but portions of the guide disappear. Resetting the receiver clears this problem up. I've reset my HR22 now 4 times--wondering if perhaps I have a faulty receiver? No other problems other than those related to Guide responsiveness. Thanks!
