I just updated my Panny DMP-BD55 to the DMP-BD85K since several discs wouldn't play. Several options were listed for the HDMI color output when I did the set-up. Not sure what to select. The options were, HBMI RGB, HDMI RGB enhance, HDMI Yc.... (4:4:4) and one more that I can't think off right away. What do you think??? Also, do I need to recalibrate my color???????
