change aspect flag with Avidemux

[hd200]

How i can change avi file flag to 16:9, i want copy video and audio then change only aspect of avi file because by default it is 720x480 squashed and i have to manually set 16:9 every time.

I think in Avidemux you can't do that without re-encoding. Use MPEG4Modifier instead...
