Ken, I run into the same problem with my TiVo and my Denon.
I'll be unsure until I test it, but I think my HDMI connection also causes some of the "dropouts" I get when Pandora switches to and from it's "screensaver" mode.
I've always found it very irritating to have music "drop out" at all, or even to suddenly, for example, stop a CD or turn off a receiver when I've been listening at a substantial volume. I always have to turn down the volume before shutting it off suddenly.
That little blip with Pandora's TiVo and/or the Denon was one of the reasons I asked about HDMI handshaking issues recently.
