I think someone with enough time could make some sort of faq on playing videos so people do not have to make pointless topics on playing videos. You now like how you need to install DivX and stuff. Just an idea
People just need to read more thoroughly and have more patience. When I look at run I read the requirements, authors notes, everything. You could make as many topics as you want, there are still people who just look for the download and don't want to do any research on getting everything to work properly.
