It seams that it doesn't like data I saved before with
vfw2menc, but if you call first GETSTATE then rewrite it
with SETSTATE, the codec will not complain.
vdub uses a different way
it seams using mencoder the codec writes
a key in HKLM -> HKLM\bSettings while it writes the correct
key HKLM\Software\ON2...etc while used in vdub
This codec really want to mess my registry,
a non admin may be not able to use it.

I've stepped a bit the codec it currently writes data in the registry
but returns 0 on SETSETATE message, I've made several tests
without any result, anyway it seams that vp7 video are not currently

agree, but some codecs still work without like vp6vfw.dll,
btw vp7vfw needs com to embed IE into the about dialog...
a bmp it's not enough? :D
