Completed some TODO in wxMMedia (wxSoundUlaw, ...) Reworked the PCM converted: it should be simpler to add converters now and it is cleaner. Implemented status information in wxVideoWindows but it doesn't work on my Win98SE (UNSUPPORTED_FUNCTION) Changed *ERR into *ERROR Added a TODO: we must detect the best format in wxSoundWindows git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@6311 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
