I am having a VERY strange problem. I am using a Canon HV20 and connecting it via HDMI to the HD-Connect MI. When I preview the video, I am getting a reversal of color (basically, the red colors are blue, and the blue colors are red). At the moment, I am running things in SD mode (I want to upgrade to HD - but not an option at the moment).
When I connect the HDMI cable to my preview device, there is no color reversal. When I leave the system in color bar mode, there is no reversal. It is only when it connects to the HV20.

Ok, I have discovered the fix.
Basically, it appears as though the HD-Connect MI is selecting the wrong color space. The fix was to downgrade the firmware to version 1.1.35 (I discovered this because it was the version that had a fix associated with the HV20 - the current version selects the RGB colorspace, for some reason).

Hi Jeff,
Thanks for notifying us of the issue. The HV20 is a bit different because it transmits in 4:4:4 YPbPr colorspace. I'll take a look at the issue and put in for a fix on the next software release.
