Windows programs that can add audio to video without re-encoding?
 

Can anyone point me in the direction of such a program? I want to add audio to a video without having to re-encode either. Is there any free software that can do this easily? It's so easy on damn Macs, you'd think there'd be a similar way effortlessly to do so on Windows.

Thanks for any suggestions.

Virtualdub maybe? (Use direct stream copy for the video).

Alternatively, if you're not hooked on .AVI, mkvtoolnix can mux in all sorts of audio and subtitle streams into an existing MKV file.

VirtualDub, yeah... the video file's in .mov format though, and it's already compressed to hell. Does Media Player Classic have this feature?

Actually, MPC will do that. When you open a file, you have the option of setting a 'dub' file. It doesn't SAVE with the new audio, but you can watch it with the substituted audio.
