Centering Video in VirtualDub...help please?

I recently changed a video aspect from 4:3 to 16:9 using VirtualDub. The resulting video looks pretty good, but when I play the avi in WMP, the black margin is all on the top. The video is not centered evenly between the top and bottom. I looked all over for some tick box or something to let me center it that way...but didn't find one.

How do I center the video on the screen so there is a black margin at the top and bottom evenly instead of a wide black margin at the top and no margin at the bottom?

Thanks in advance.

 

If you drag your new avi back into virtualdub?
Is there any margin at all, top and bottom?

 

Nope......I even resized the viewing screen and there's no margin anywhere in VD.

 

Then you must be having a problem with the media payer and/or the codecs
involved. Try running it in VLC or some other third-party player.
VLC's probably a good choice because it uses it's own internal
decoding.

 

Thanks Dave! It WAS Windows Media Player! I put it in 2 other players, and it was fine! Hmmmm. Never really liked WMP that much anyway, but I took your advice and d/l VLC and will give that a try as my "main" player from now on. Thanks again! KUDOS!
