I have the same DVD player used with a SXRD and I can't recall anytime that 16:9 images have had problems being displayed in that aspect ratio. Is this small box really small or is it just the 4:3 ratio with the 2 vertical black bars on the sides? Is there a video mode on your TV to tell it to automatically display any image in its original format (i.e. no 4:3 images are stretched to fit the whole screen and 16:9 fills the whole screen)?
I just got a Sony DVP-NS75H. It's playing through a Sony XBR-400 TV. Everything's working fine for enhanced DVDs. But when I put in a non-enhanced disc in, it appears in a smaller box on the tv screen. The TV is on auto 16x9, but it seems I have to manually set the DVD player to letterbox. In other words, there's no auto 16x9 in the DVD player's setup menu.. the only choices for TV type are: 16x9, letterbox, and 4x3. Am I missing something here?
