The question is whether the cam provides the codec as an independent
component, or if it's embedded in the crapware that does all the other
camera stuff. If you want watch movies from the cam using WMP, it
should be easy to get MPlayer to load the codec. If not, it's probably
not worth trying. Next time just buy yourself a proper piece of
hardware that's not intentionally obfuscated...
