not sure where to post this, but it does relate to ps3 as well as regular and hd programming.....I have a Phillips 1080p 42" LCD TV. I have noticed on my tv (as well as several other brands) that while watching, the picture seems to expand for a few seconds and then contract while watching (kind of hard to explain). Is there something I've done wrong in the picture settings or is this common? any help is greatly apprciated.
