I dont know what Ive done. Ive used VirtualDub for a long time now but lately somethings changed in the way aspect ratio works in a movie. If I have a movie and render it with VirtualDub without anything but run a full processing mode and any codec the result - played back in VLC changes the aspect ratio after 1 or 2 seconds. I can change it back in the VLC settings - but why does this happen? I want to make it work like it did before since the problem is annoying especially when palying back on at TV.
