Known problems were posted recently. See
http://article.gmane.org/gmane.comp.video.ffmpeg.devel/57399
and
http://article.gmane.org/gmane.comp.video.ffmpeg.devel/57274
The changes discussed here are purely cosmetic. So, no, they won't

As should be obvious by this thread, current SVN does not yet contain
complete PAFF support.
