My problem is that when I hit play for a video that I made in Movie maker the screen is completely black. However, there is sound. And I know it's a video issue because the video does open up and is editable in Lightworks. It's just Movie Maker which is what I want to use. I've searched through all of the topics, tried to update drivers, etc. but nothing is working and this is really bugging me. I have the problem with videos if they are mp4, avid and even wmv. Oh and the same videos that won't show up to be edited in WMM I can see them fine in Windows Media Player.

I would definitely appreciate any help. I have Windows 7 64bit
