Please make sure you have the correct and uptodate packages installed and at least attach your Xorg.log (probably best to run apport to grab all the info).

Unable to run/view HD videos at all Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: *** I reported this as a question on Ask Ubuntu and was told this is a bug. http://askubuntu.com/questions/245584/choppy-and-pixelated-video- on-macbook-air-5-1-unable-to-run-view-hd-videos-at-a *** I'm currently running 13.04 and the video is extremely choppy and pixelated on any video program I run (vlc, mplayer, totem etc.), any flash or html5 videos, and HD videos won't play in a reasonable way at all (entire frames get skipped and video footage is completely distorted; I would say it's about 10 FPS on HD videos, really extremely bad quality). Also, I had this exact problem on 12.04 and 12.10 and was kind of hoping 13.04 would be better, but it is not. Video in Mac OSX works excellent, no lag or quality loss, works perfect in that OS. I would attach some sort of log file but I don't know how and would need directions to do so.
