Looking for free windows tool for adjusting aspect ratio of a VOB file.

[BloodyL]

Would like to change from 4:3 to 16:9 without touching the actual audio/video encodes.
Any ideas?

Have you tried VLC?

To put it better, I'd like to edit the video header info the file.
I'm not looking to view the video in it's corrected state, instead rather correcting a fault in the encode.
Have given VLC a bash for converting/streaming and got lost as I didn't have much time, can it do this?
Cheers.
