Almost all video-sources were/are meant to play on TV, where AFAIK NEVER square pixels are used, as in your DVD-example. Square pixels will result in more pixels without ANY benefit. Only if you need to play on devices that don't accept, iPod and others, non-square pixels it's usefull/necessary to use square-pixels. > > > > Thanks in advance! > > > > _______________________________________________ > MPlayer-users mailing list > MPlayer-users at mplayerhq.hu > https://lists.mplayerhq.hu/mailman/listinfo/mplayer-users
