--- Comment #10 from joaopa jeremielapuree@yahoo.fr --- That is not wine fault. Ubuntu (and debian) can not install the 32bit versions of some gstreamer packages requested by wine (because of dependencies). Switch for an another distro. For instance, Fedora is known to work fine with winegstreamer.
