Alternative to VirtualDub. Adding Black Borders.

Alternative to VirtualDub. Adding Black Borders. 

I'm having trouble adding black borders to the edges of an avi video I'm working with. VirtualDub 1.7.7 won't open the video file, and I don't know what else I can do at this point. Are there any other programs I can use to alter my video and add black borders? Any assistance that can be offered would be most appreciated. Thank you for your time.

Hey! I downloaded avidemux and I was successful in adding the black borders, thank you so much. But now I'm having a problem putting the video I added borders to into a DVD for my home theater. I'm using Nero 8 Ultra, and the black borders never show up in the previews before I burn the disc. I really don't want to burn unless I'm going to be sure it'll work, because I really don't want this video to be overscanned. I'll provide whatever information I can if it'll help, but I warn you, I'm rather ignorant of what everthing means. Is there another program I should be using to make my video?

I use this Asyther template (which is slightly modified avisynth script which can be easly turned into "pure" .avs.) Code:

Got black borders, now how to make it fit aspect ratio...
