Hi, I have many DVDs, most of which are widescreen. As packaging is generally pretty bad or misleading, how do I tell which films are anamorphic widescreen and which are letterboxed? My reason for asking is that I want to rip for Apple TV. I figure that the letterboxed films can be ripped in exactly the same way as my 4:3 content without making any huge sacrifices in quality. Thanks, Steve.
