You can use VirtualDub/VirtualDubMod/VirtualDub2 (Try to use 32bit as much as you can), or MEncoder/MPlayer to Encode and View the avi's encoded with these codecs.

If VDub doesn't fit your fancy for some reason (Sometimes when you install a codec driver, it wont show up in VDub) you can use MEncoders vfw options like so:

mencoder input.mp4 -ovc vfw -xvfwopts codec="/Users/Username/Downloads/igcodec.dll" -nosound -o output.avi
mencoder input.mp4 -ovc vfw -xvfwopts codec="/Users/Username/Downloads/OldAndObscureCodecs/Rududu.f i l e s/rududu.dll":compdata=dialog -o output.avi
ffmpeg -i input.mp4 -c:v huffyuv -s 1920x1080 -f avi -t 5 -an - | mencoder32 - -ovc vfw -xvfwopts codec="/Users/Username/Desktop/OldAndObscureCodecs/Loss-Less Codec Library(AVImszh + AVIzlib)/LCL223/avizlib.dll" -o output.avi

You MUST use forward slashes in your .dll path for some reason like I did above, this does not work: -xvfwopts codec="C:\Users\Username\CodecDirectory\igcodec100\igcodec.dll"

If you have trouble loading a codec with an error message like "Can't open library:" or "ICOpen failed! unknown codec / wrong parameters?", try moving the .dll to your Desktop or something and try again. Sometimes whitespace or certain special characters appear to mess with MEncoder.
