After recording the video, Fr. Chazal informed me to post this here, and also to clear some misunderstanding, namely, that his theological difference with Fr. Paul Kramer would be settled finally at the death of Benedict XVI. Right now Fr. Chazal avoids attacking Fr. Kramer's position (though he discussed this with him all too frequent) as it does not constitute any theological obligation that one must believe i.e. Benedict's retention of the Papacy, for one to be a Catholic.
I was also surprised that he has no quarrel (albeit he disagrees with them) with sedevacantists who view the "vacancy" of the See of Peter as a probable position, or opinion, without any dogmatic pretext.
