Jack,

Meridian uses digital switching so think of the 6 HDMI inputs in the HD621 as actually 6 discrete audio inputs and 6 discrete video inputs. The last valid tag box is used for setting up audio sources that do not have a matching video input.

You set up "Last Valid" for the video input of the SACD source. Then if you want to watch TIVO while listening to SACD, you would then simply select the TIVO first, then switch to SACD. The audio switching would change independently from the TIVO to SACD whereas the video switching would remain unchanged from the "Last Valid" video source, which was the TIVO.

This is how it should work unless anything has changed.


Cheers,


Steve
