Best software to convert video to a different aspect ratio for various screensizes [closed]

"I sometimes get .mp4 and other video formats whose aspect ratio is clearly off
What apps do you use to reconvert such videos to an aspect ratio better suited to to fit either a regular desktop or LCD screen size?
Hopefully with little or no loss of audio/video quality"

"VirtualDub comes to mind. I use that one to turn video's 90 degrees.

I think also SUPER can be used for this.

Edit: As for your question concerning file size or quality loss. This totally depends on what codec you re-encode to and with which parameters. You can use gspot to see most of the parameters of the original file, and if you specify everything the same (except for the aspect ratio of course) the file size shouldn't be much different and there shouldn't be no quality loss.
If the source file is e.g. an mpeg-1 file, then you can re-encode it to mpeg-4 and make the file much smaller while maintaining the same quality (all depends on parameters of the re-encoder of course)."

"I used MediaCoder for converting videos for my PSP which involved changing the aspect ratio and it worked really well.

MediaCoder is a free universal media transcoder since 2005. It integrates most popular audio/video codecs and tools in an elegant and transparent manner into an all-in-one transcoding solution. With a flexible and extendable architecture, latest codecs and tools are updated added in constantly. MediaCoder intends to be the swiss army knife for media transcoding in all time."
