I use vlc player. I would say that is it one of the best media players out there with its light-weight design and customizable interface. I used it for quite a white and it never had any bugs or crashes. Try uninstalling vlc and downloading the newest version. I remember mine was crashing all the time back in the day so I reinstalled it and there were no more crashes afterwards. There are lots of other near features too. If you don't know where to look then check out the vlc player download page. Here's the link to vlc player download page if somebody doesn't know what it is.
