I have my TiVo Series 3 hooked up to a Denon 3808ci receiver via HDMI. I experience frequent audio dropouts, but only when watching live TV through the TV. If I back up a few seconds and rewatch the same segment after it's been recorded, there is no dropout. When the sound drops out, the "digital" symbol on the front of my receiver disappears as well. The fact that the dropout is gone on the replay suggests to me that this is not a problem with a cable signal. Does anyone have any idea what could be going on? I'd really appreciate any help. Thank you.
