I have a Pioneer plasma TV that I just discovered handles RGB better than 444 which is what my S3 is putting out. Using the Spears & Munsil chroma pattern on an Oppo 95, RGB shows more resolution on my display than 444 does. I understand that this may very well be unique to Pioneer plasmas so you milage may vary. I tried rebooting the S3 with the display set to RGB in hopes that the S3 would see it during the handshake and change the color space but no luck. It continued to output 444. Any suggestions? As a side question, I thought most content was mastered as 422. What's Tivo doing converting it to 444?
