I need help understanding different aspects - when they occur, what is standard, etc. I've been irritated because sometimes when I view a widescreen DVD I still get black bars on the top and bottom. Isn't this TV a widescreen already? If I switch from "Full" aspect to "Just", it stays the same. If I switch to "4:3", its obviously wrong and squished. "Zoom" might get rid of the bars on top and bottom, but then obviously the picture is cutoff from the sides (can't see half the name when the credits scroll by, etc). What is the deal? I note that I can fully tweak zoom and stuff in the DVD player's extensive menu. But there is never a perfect setting?? Setup: I've been the happy owner of a Panasonic 42" plasma (TH-42PD50U) EDTV for about 1.5 years now. I have a matching Panasonic DVD player connected via HDMI.
