Just got a Hughes HDVR2, which was an upgrade from a 2 year old basic RCA DirecTV receiver. I'm finding that the channel surfing is markedly slower, as is scrolling through the program guide. Is this normal? Is there anything I can do about this? Also, every time I push a button on the remote, there's an annoying "bip" sound that accompanies it (not from the remote itself, but from the satellite audio). Is there a way to disable this? It's driving me crazy!! Does anyone else who owns this receiver have any insights or opinions? I'd be interested in hearing them. The fan is kinda annoying as well. I haven't explored the Tivo services yet, so hopefully they will make up for the receiver's shortcomings. Another question: someone told me that using the optical output for audio will slow down the receiver even more. I'm not sure if I buy this. Is it true? And aside from the occasional HBO movie in 5.1, is there any sonic advantage to using the optical audio output? Any opinions/responses would be appreciated. Thanks!
