I have been using windows live photo gallery as a video screensaver on my windows 7 64 bit system for a few months now.
For some strange reason it has stoped playing WMVs for no reason.
If I go into the screensaver settings and in the preview it displays the following error.
The screen saver can't start because there are only videos in your selection.
This has not been a problem before.
The videos play fine in windows media player and play in live photo gallery.
I have tried to reinstall the live photo gallery and this does not resolve the issue.
I also used to be able to change the display template of the screensaver but for some reason i cannot find this option anymore.
