I bit the bullet last night and got the 'official' mic for the receiver but was a bit miffed that after having spent close to $1K on it that I had to go out and spend ANOTHER $70 just to get it configured through one of it's prime selling features. Adding insult to injury is the fact that the 2805 comes with the setup mic gratus. I can tell you that mic sure didn't feel like a $70 piece of equipment and it sucks to spend that kind of money on something you might use ONCE or TWICE ever in your home theater setup. I have a el cheapo computer mic with a stand that I think I spend $4 for at Frys Electronics that I'm going to mess with this weekend and I'm going to shoot some digital camera shots of the screens just so everyone can see how well the $70 mic compares with the $4 one and see if it's really worth the expense. I was just wondering if anyone had actually done this yet themselves that has the receiver? On a side note, is there any button on the remote that comes with the AVR-3805 that you can use for the "Guide" on a TIVO unit? I programmed my remote last night and can get most fuctions to work but haven't figured out how to get that one going yet.
