Equipment
Mitsubishi WD-65833 DLP
TIVO Series 3
Toshiba HD-XA2 DVD
Onkyo TX-SR605 A/V Receiver

QUESTION
I have the TIVO and DVD player plugged into the Onkyo via separate HDMI inputs. The Onkyo then outputs to the display via a single (shared) HDMI.

Am I correct in assuming that it's possible (perhaps even likely) if I calibrate using a DVD (Get Gray) I'll get proper calibration for the DVD but that the TIVO will be off? If so, what's should I do? I obviously want the sound going through the receiver for DD output.

Thanks
