Sometimes it could "goof" in the 1.0x release and not switch 100% correct between RGB and YCBCR sources. That's when you see something come out with the wrong color. Also have not needed to cold restart the HD621 since 1.10. Sometimes in 1.0x I could need to do a cold restart when source did not display. It was VERY SELDOM, a couple of times a year. But this haven't been an issue with the new firmware.
