For some reason something in my settings has changed... I lost the ability to adjust my television viewing modes while watching DVD's. I have the Samsung 42" Widescreen(1080i) which normally lets me adjust my aspect ratio on the fly during DVD playback. Now, all of a sudden when I go to adjust this, I get the "Not Available" pop up. I have the Samsung P421 progressive scan DVD player and its video option settings have been verified at 16:9 Widescreen. My TV is defaulting to Widescreen for some reason, and even if i turn my DVD player off and set the component video input to "DVD" it forces itself back to wide once I play a DVD. The aspect ratio is adjustable for every other input on my set... so my guess is my DVD player has something to do with the problem. This problem just popped up out of the blue Was working as it should (able to set aspect during playback to "DVD" I'm stumped Any ideas??
