Yes actually, in the past few minutes I hit on a good google search and came up with this: http://askubuntu.com/questions/233510/how-to-fix-video-playback-showing-green-screen-with-just-audio.
I had forgotten about VLC player. The problem in this post was exactly the same. So I downloaded it and turned off the accelerator and VLC works perfect. It wins the default spot! Was a clean and easy install too.
I would still like to get WMP working so if anyone has ideas I will take them. But there is no hurry at this time. I never look at the recordings. If I don't get an email alarm, or if it was a false alarm, there is no point. But if I had a real problem, I need to be able to provide the videos to law enforcement fairly quickly, VLC provides that.
Thanks everyone. Again, if someone is familiar with a WMP fix for this it would be appreciated.
