I tested the patches one by one, and 0003-winegstreamer-Flip-video-output.patch is the one that breaks video playback in Powerpoint 2007. With just the first two patches, both audio and video playback are normal in Powerpoint 2007, and the video even plays in Powerpoint 2010, but upside-down and without any audio.
Thanks. I wonder if you're missing the videoflip filter? In my distro, it comes from the gst-plugins-good package, in the file /usr/lib32/gstreamer-1.0/libgstvideofilter.so. If you want, you could attach a log with +tid,+gstreamer,+quartz,+strmbase,+qcap,+qedit.
