I created a movie yesterday using the original movie maker that came pre-installed on my HP Pavilion 6 desktop PC. I am on Windows 7. When I burnt the video to DVD, it wouldn't play on a DVD player, or someone else's computer. Looking at the forums I was recommended to upgrade Movie maker. I did using the Windows essentials. Now I can't open Movie maker at all. I get a message saying I need to check my system requirements. I have the latest updates, and my Intel graphics card seems to be ok. I can't use the Intel site to upgrade because they say that the card is a custom card and needs to be upgraded via the PC manufacturer's site where there doesn't seem to be any upgrades available. Please assist.
