To introduce myself, I am a first-time H/K owner and so far am very happy with the purchase. I have an AVR 247, April 2007 build (seemingly no build issues - *knock on wood*). I am new to the home theater topic, so I apologize if my question is basic stuff, but here goes.
My question requires a bit of background. I have a Motorola DCT6416 III HD/DVR STB from my local cable company. IMHO, not the best quality machine in the world, but they didn't ask me. Go figure. I run the HDMI directly to my TV (Panasonic 50PX75), since I don't really like the way the 247 scales SD pictures. Not a problem. I have run an optical cable from the STB to the 247, for when I want to pick up the DD. This problem has happened to me twice: When watching a recorded program on the STB, usually after either fast forwarding or rewinding the program, the sound signal going to the receiver is lost. No sound at all, and the two L and R boxes on the display start blinking. The receiver flashes "2/0/.0". If I switch to the TV speakers, all is well. The first time it happened, I'm not sure what fixed it, but it did. The second time, I powered down the STB and powered it back up, and it seemed to work again. The 247 is only about 2 weeks old, and my question is, does this sound like a receiver problem, or a STB problem? My guess is the latter, but since my return period is dwindling, thought I would see what your guys might think.
Associated with this is a minor issue, whenever fastforwarding or rewinding a program, the sound delays and there is usually a noticeable boom from the subwoofer as the sound kicks out, and back in when it starts playing again. Is this a normal reaction from my sub?
I appreciate any insights you might be able to share. Cheers.
