Ok, so we recently bought a Pioneer PDP 5051, yeah, same thing as the 50, any ways... I setup the sound system, TV, HD Cable box from Time Warner, all that... For the first day or two, when viewing our cable programs, we were able to select all of the various screen sizes... Now, it's only switching between Wide and Full... I read the manual and it said those are the two options i'll be able to choose from when viewing HD programs... Ok, well, why was I able to switch through Cinema, Full, Wide, 4:3, etc, initially and why can I no longer choose those other options? I've tried everything and still no cigar. Wide and Full sucks... Wide, it warps the screen and Full gives me two letter boxes on the left and right side (up and down, not horizontal). What can I do to switch this around? HDMI Input? Any suggestions would be appreciated.

Thanks,
