Strange orange "flicker" with XBox 360 as extender
I have been using an XBox 360 as a WMC extender. I just purchased a new TV (Samsung plasma) and thought there might be something wrong with the TV since when watching a football game in WMC on the XBox 360, most orange objects (first down markers, end zone pylons) had this strange shimmering/flickering effect when displayed. I have determined it is the XBox 360 and not the TV because playing the same clip on my WD TV Live player using the same HDMI connection and resolution to the TV produces no flicker effect (the orange objects in the clip are out-of-focus and blurry but don't have the distracting shimmering of the 360). Likewise with the built-in DLNA player in the TV.
Here is a small clip (26 MB, .ts) that shows the effect. Look at the first down marker on the sideline and end zone pylons as the players go by: http://1drv.ms/1zssg0o
I have tried both 1080p and 1080i output with the 360 but it makes no difference. I tried changing the Reference Levels and Color Space settings but it seems to make no difference. Any ideas here? Thanks for any help.
