dragonplayer fails to play video

[Darin Miller]

Attempting to play mp3/mp4 video with default Nouveau drivers fails to render any video. The player resizes to the aspect ratio of the video and audio is played, but no video. No change in behavior after installing kubuntu-restricted-extras.

Installing proprietary NVidia drivers "fixes" the issue.
