Ken,
I'm working with Dean at CQC as well to evaluate the beta 990 driver. I haven't purchased CQC yet, but I like what I've seen so far in my evaluation.
I've been messing around with creating an interface just to test out the 990 driver. A few quirks here and there, but CQC seems to be doing its job.
The latest bit of odd behavior is that when I send the "select DVD input" command, I get video 1. When I send "select video 4" I get DVD. Some of the other video inputs are messed up too. I'll email Dean about it.
Doing a macro to iterate through the settings is what I was thinking. Unfortunately I haven't figured out how to get everything that I can do from the remote & front panel to work through CQC. For example, if I've got some DTS material playing, I can send commands to switch between DTS and DTS:Neo 6 and that works fine, but I'm not able to change the Dolby modes (which I believe are controlling how the rear channels are decoded in a 7.1 setup). I can do that from the remote.
Also, I haven't been able to get things like turning the front panel dimmer on/off to work, though that is probably my own unfamiliarity with CQC.
Overall it's pretty cool though. My current thinking is that I'm going to run CQC on my HTPC, using Zoom Player to play back content out of the DVI output to my projector, and the VGA output will connect to a Xenarc or Lilliput 8" touchscreen. The touchscreen will be set up as the primary display and will contain the desktop and run the CQC interface. If I can make it work, the projector will never show desktop or menus, just content. Much more cinematic in my opinion.
