This never happened before I added the 103D to the mix.
It is entirely up to the source device (the TIVO in this case) whether it initiates a new HDMI handshake when it doesn't HAVE TO. As long as the channel you are on and the channel you are going to have the same characteristics, there's no need to do a new handshake, but the TIVO might be too stupid to implement it that way.
Also, some of these boxes go bonkers when you bring up their menus -- including channel guide. I.e., they force a new resolution to display the menu -- and thus a new handshake.
Now, if you are using "native" video resolution output, and the two channels have different video characteristics (1080i,720p or 480i) then there has to be a new handshake -- that's just the way HDMI works. That will take a minimum of 2 seconds as delays are built into the handshake spec to allow slower devices time to dawdle along. If something goes wrong, a handshake "retry" happens. So the time to new video/audio may be longer, in multiples of 2 seconds.
If you want best video quality, you learn to live with the handshakes. If you can't tolerate the handshake delays, then set the TIVO to a fixed output resolution (e.g., 1080i) and just live with that video quality.
Complaints to HDMI.ORG please. But you'll need to queue up. There's a LONG line at their complaints window.
