I have done lots of converting in the past and present, but sometimes come across video files that are in the format I want but have the wrong aspect ratio. In Media Player Classic i can still watch normally by "override aspect ratio" but i would much rather change it permanently and not have the hassle of changing back and forth from aspect to aspect depending on the video. the reason why i think this could be an easy fix is because when you play a file, obviously the media player has to know how to play it with a set of parameters right?

Is there a way to change these details in Windows 7 or even maybe a 3rd party program?
