can someone assist me to change the aspect ratio of avi file with MPEG4Modifier. i am new to this software & cant find a guide the problem is when i play this on windows media player, the movie is all stretched up & when i open it with virtualdub & then change the aspect ratio to 16:9 (wide screen), the video looks just perfect. (actually from where i downloded this, there was a note stating "set aspect ratio manually to 16:9") any help will be much appreciated & i have a few more files with exactly the same problem but they all have different frame sizes, like one is 512*384 & so on.

It works quickly just try the various options till you hit the right combo. Start first with Display AR-> tick 16:9. If that doesn't do it try ticking (changing) one of the NTSC options in Pixel AR also.
