4cc codes for MSU, corePNG or lagarith

[yair]

i know it should be an easy google search,
but im looking for the 4cc codes for MSU, lagarith and corePNG and cant find it.
found many fourcc code lists but none with this ones,

* http://www.timtaylor.net/fourcc_codec.htm
* http://lags.leetcode.net/codecstats.html
* http://www.fourcc.org/codecs.php

or a program that scans my codecs and spits out their code (hopefully a switch in mancoder/ffmpeg)

im on windows, btw.

i rediscovered code sniper (http://www.videohelp.com/tools/Codec_Sniper), it has that option.
MSU=msud
lagarith=lags
corePNG=png1

quicknote:
does anyone know how/if i can register new codecs with mancoder's libavcodec.
it complained on everyone of those three.

best list i found is in the multimedia.cx wiki:
http://wiki.multimedia.cx/index.php?title=Category:Video_Codecs
or at http://codec.kiev.ua/ (legal?)
