i'm not sure, if i understand your question. 'i_certify_...' was a flag,
that had to be used with old versions, i mean it was mandatory when
streaming into something different than the avi-container. with new
versions, this flag doesn't exist anymore and therefor causes an error
when used. since i am used to use a fresh svn-checkout, i didn't use the
flag in my first mail, but i added it in the second post (that i
accidently first sent only to javier instead to the list).

confusion ;-)
