I was wondering what anyone out there with a PW6 / PW7 use as an aspect ratio when watching the PW7. I've been using 16:9 for Sky, and although it stretches the picture a bit, it's still better than possibly damaging the screen. But when watching DVDs I've noticed that 16:9 seems to hold it to what seems like the correct aspect, i.e. no stretch. When I put it on 'Panasonic auto', in which I thought was supposed to work out correct aspect, it seems to stretch the picture vertically. Any thoughts on this? Also wondering whether watching a lot of DVDs which are going to have black bars at the top and bottom of the screen will damage the screen in the long run?
