How do I correct a wrong aspect ratio in an XviD-file?

[eterna111]

Hey there, I was how I can adjust the settings/encoding of an XviD-file I have. It's currently playing in 4:3, but I would like for it to automatically play in 16:9 (which is the correct one).

Here's a videosample:

(5MB, direct download, no waiting)

Can I adjust the settings somehow so it "knows" it's a 16:9 file?

Thanks for any answers :)

Install .net 2.0 (and SP1), download and install "mpeg4modifier" from moitah.net (no installation, only copy into target-folder), load avi-file, set "Pixel A"R to 16:9 (PAL or NTSC) and save avi, that's it. Setting Pixel AR to 16:9 can also be done in xvid for encoding.

olnima: MPEG4 modifier worked perfectly! Thanks so much for the tip, this program will come in handy for later use as well, I'm sure.
