Well... I went and looked at the manual about the DSP Presets and changing them, saw the field you were talking about Carl and then went into my Config Program and those fields were not present in my multi-channel movie presets.
So... I decided to update the firmware. Oh joy! It's really painful... but I finally got all of them to go through and then went into the configuration from the start. When I got to the center channel I deselected the 96KHz/24-bit Capable field, finished up the configuration and went through the calibration.
Once again everything was there... I don't have the mic to do the room calibration (but I will by Saturday so I can complete it)... finished up the config and it uploaded to the G68.
I fired up the Bluray, and the center works! Woot!
I'm pretty sure it was just the 24-bit Capable stuff that threw the system into a tizzy. I'm looking forward to watching a movie on the big screen tonight and seeing what a difference it makes. It's (literally) been 10 years since I've had a system really set up for movies in the house. I had a really good system in the house in town, but when we moved to the country I didn't have a dedicated theater space and once I got this Meridian system it sounded so good as it was in stereo I just never had the drive to go the next step.
I'm working on convincing her to let me hack up her newly painted walls to install the DSP420's for surround... this should be a fun battle. Wish me luck
Thanks for all the support...you guys rock.
