Got my Roku 2 XS delivered today.
I can do a direct comparison with my Panasonic BD-65.
Content via Amazon, which I have used with the Panny since the beginning of this year.
The Roku 2 XS image is much darker, something is wrong with it (build 2663).
Justified Pilot, Boyd just blew up the church and is ready to put one in the back of the dudes skull in the jeep.
With the Roku 2 XS, their faces are black blobs with 2 glowing eyes, looks terrible but on the Panny it looks great.
HD content is softer on the Roku 2 XS.
Also getting a crackling sound through the speakers when scrolling through the channels.
Browsing is much better on the Roku and the thumbnails when going forward / reverse in titles are a huge help, nothing like that on the Panny.
But PQ counts and it's lacking with the Roku. If I can't get the black levels fixed it's gonna have to go back.
Apparently the Roku 2 sends out a Full color space (RGB) signal instead of the more typical Limited color space (YCbCr). There are no settings in the Roku to change this nor is there anything that says it's doing something different.
The 'fix' (if you have crushed blacks, bad saturation, etc. with the Roku) is to change your tv's HDMI settings to Full.
If your tv is already set to Full you are good to go, but if you don't have the option to change to Full your are SOL for the time being.
Of course if you do change your tv to Full you will have to change your other devices to output RGB too. In my case I had to change the digital cable dvr, Panasonic Blu-ray player and X-Box 360.
Once all that was done the PQ on the Roku 2 XS looks the same as when I was using my Panasonic BD-65 for Amazon Prime.
