This is a little hard to explain, but when a DVD starts playing in the DVD Player application on my iMac, there is a weird border of about 1 pixel all around the edge of the picture that seems to be mirroring what's on the opposite side of the screen. For example, if there's something like a space battle happening (i.e. with a dark background filling most of the screen) and a ship explodes at the bottom of the screen, I'll see a thin, bright orangy strip of that explosion also up at the very top of the screen. Oddly enough, this doesn't happen if I go into Front Row and play the DVD through there, it's only in the DVD Player application and only in full screen mode. Not a huge deal, but it's just really annoying the heck out of me. Any ideas on what might be causing this and how to fix it? Thanks!
