This may seem an odd question, and if covered before my apologies, but does anyone know of a way to watch 4:3 video as 16:9 on a computer screen? I'll explain. For purist out there this may be anathema, but with the Apple DVD player it is simplicity itself to stretch old 4:3 video to fully cover the wide aspect screen, such as a MacBook. The result is a picture obviously somewhat distorted, but otherwise without the vertical bars at either side, and mimicking content filmed at 1:85.1. However, as far as I've discovered, this is only possible if using a DVD, and then of course the DVD player software which allows this to be easily done. The problem lies with video from other sources, such as Amazon Video on Demand, or that from iTunes, since not a DVD and using that software adjustment capability. HDTV television sets usually have this capability, in easily being able to adjust the aspect ratio, and to fill the wider screen with video content that originally would not. But what about computers? Is there some piece of software or technique which would allow stretching 4:3 video to 16:9 on the fly? Thanks for any ideas.
