hi, after i find the Erik already checkin the update to newer crt and header and able to fix the d3d patch now (for me) everything build on rhel-6. so Erik svn contains spec which is working on both fedora and rhel-6. i'm just rename mingw-gstreamer-plugins-bad to mingw-gstreamer-plugins-bad-free as in fedora since the current mingw-gstreamer-plugins-bad was actually mingw-gstreamer-plugins-bad-free. i'll create the other (rpmfusion corresponding) mingw-gstreamer-plugins-bad an mingw-gstreamer-plugins-ugly build on next week. and hopefully finally will be abl to start to work on the filesystem enhancement to cleaner spec file management. regards.
