I have some short MPG clips I am trying to assemble into a DVD. If I play the MPG's in Realplayer or WMP, they seem ok until I try to go fullscreen. At that point, the video is seemingly crushed down to around 16:9 , but everything is short and wide. The clips play at normal aspect if I don't go fullscren. After loading the clips into Nero 7, I can see by the thumbnails that the same thing is happening, ie they are getting compressed, squished, squashed, basically messed up. Any tips or pointers? Is there an app that I can lock the aspect ratio for this format?
