[ubuntu] white line at bottom of video

http://ubuntuforums.org – Greetings-- I've been having a problem with playing some videos from my DSLR. There's a white line at the bottom of the video. (Not really white: it's all different colors, but it mostly looks white.) See the attached screenshot. The strange thing is that it doesn't happen with all the videos from that camera. But it is consistent with each video and across players (mplayer, totem, ffplay). The camera is a Canon T3i. The videos are 1920x1088 (1080p), 24fps, H.264/AVC in an MOV container. This is Ubuntu 12.04, 64-bit, on a Macbook Air 4,2 (Intel graphics). Thanks! (Hardware)
