Hi, I'm trying to remux a divx avi file to change the preload. I need to change it on multiple files from about 32-100 to 500 ms.

I've been trying to do that with VirtualDubMod, but it doesn't change anything! Once, it changed the interleave settings, but it doesn't do anything with the preload times.

Here's what I'm doing:
Open video file
Video->Direct stream copy
Streams->Stream list
Right click, Interleaving, then I leave everything the same because 500ms preload is the default
File->Save as.

I followed a guide, so I'm not sure what I'm doing wrong. Thanks for your help!

EDIT: Oh, and I'm diagnosing the file with GSpot B01.
