"There is a codecpack that helped a lot of people with video or sound problems"
Q: Game crashes upon playing intro videos.
A: In order to display the introvids, the latest videocodecs are required. There is a codecpack that helped a lot of people with video or sound problems. The k-lite-codec pack can be found here:
