I have some xvid encoded movies and i was wondering if there was a way to increase the volume without re-encoding the video?

Grab VirtualDub, you can set it to only modify the audio track and leave the video track alone. http://virtualdub.sf.net

Virtual dub doesnt work on my computer.

Like everyone else on this forum, I will be mean by saying www.google.com

I would say thanks if i hadnt already tried that.

Try www.videohelp.com, mabyee they can help you.

You should try READING THE MANUAL. Here, I've scanned the relevant page for you.

Have you got the volume limiter thingy switched on in the settings menu? If so, try turning that off and see if you still feel the need for increasing the volume. .
