Movie playback duration

Downloaded Man with Two Faces, but only plays for a few minutes after buffing. How to correct to play full length of movie?
Answer #1
Buffering a downloaded movie? Sounds like you got a corrupt download mate, re download…
If you think its a codec issue, just use VLC, it uses its own codec’s and has codecs for most all of the popular formats.
