This issue solved below
I've tried serveral clean installations of the win32 installer and I can't get video to show whether or not Phonon is enabled. Then I tried setting up a testing environment "http://wiki.openlp.org/Testing:Windows_Testing_Environment" and that plays video with and without phonon. I'm not sure where to begin debugging this. Anyone have any ideas on how to fix this or atleast find the problem?

In order for most people to install OpenLP on Windows, we have to compile and build it so that Python, Qt and all the other it needs are built it. When you run OpenLP from a testing or development environment, it is running "natively" - i.e. without any bundling. This could be the reason.
That said, a fair number of folks have had success playing videos using the Windows build. I cannot say why or what their setup is, as I use Linux, but maybe someone else who runs Windows can comment and tell you what they did.
Ok. So I was able to hear the sound of videos but not see them. The transparent window that was supposed to show the video was there, but no video. I was able to get it to work by installing ffdshow, then configuring/enabling the decoding for the video I was trying to view. Specifically mapping all the wmv codec to wmv9. So ffdshow is necessary for making it work.
