Low Profile: Thanks for the spreadsheet. That's very useful.
proudx: My automation system, Cinemar, has a driver specifically for the 7000. Fortunately I've never had to worry about the exact RS232 codes: I just used the commands that the driver provides. I looked through the documentation for the driver to see if there was something like you suggested. But I didn't see one. Unfortunately, as Low Profile confirmed, the changer doesn't provide a code for that.
If the Integra allowed me to set EDID information on the HDMI connectors, I could use that to trick the 7000 in to using the right resolution. It
does allow me to set the HDMI output resolution via RS232, but that's not very helpful.
If you've never changed resolution on the 7000, it is a non-trivial process. Ince you find the right menu and choose your new resolution, the changer asks you to confirm twice (once at the new resolution and once at the old resolution) before committing the change to ensure that you didn't choose one incompatible with your display. As a consequence, trying to get an automation system to go through that process is out of the question.

latest blog post has some musings on this topic, along with other improvements I want to make to the theater.
