Wow! I didn't know gaming is strong around here.
Have someone heard about this issue
with the latest Xbox Dashboard update? It seems to give wrong black level with videos while console is set to output Expanded RGB range (0-255). Well, sticking to Standard (16-235) is not a bad idea, either.
Do you think that going with 0-255 gives substantially richer picture? Why are the TV sets not always capable of recieving and displaying it properly without clipping? I think nowadays it won't be any challenge to make optional switching between Limited and Full RGB range like Samsung does for some time. It would certainly make things a lot easier for gamers.
