is there a way to automatically change the aspect ratio flag of a video so that it displays in 16:9 in all video players WITHOUT reencode? Quality loss is not a concern. I just need a quick and efficient way to convert several video files to 16:9 as quickly as possible. For instance, older tv show series. I use a plasma tv for my media center, and do not want black bars burnt into my screen when people that dont understand how to use the zoom function in WMC7 watch tv all day. thanks.
