They support hw acceleration on Linux for anything other than the nvidia propietary drivers. (Well at one point they had support for Intel PVR chips...) As far as I am aware we (Intel) have not made any inroads into getting them to support more hw. > Also, the same problem occurs for html5 videos which I think, correct me if I'm wrong, is open source on youtube. If you are referring to chrome, then it is about as open source as code dumps many months after the fact can be... But we are working with them. WebKit itself seems to drift along failing to get acceleration to work, as the original code base is completely adverse to GPU acceleration. (And our efforts here are sadly not aimed at the desktop.) Firefox should pick up support through gstreamer, eventually. Thinking about the skips: Can you switch to a console with CRTL-ATL-F2, login and stop lightdm (sudo service lightdm stop). Then launch X and start playback: $ sudo Xorg -ac -noreset :0 & sleep 5 ; DISPLAY=:0 mplayer -fs '/home/user/Downloads/Crossroads: Labor Pains of a New Worldview | FULL MOVIE.mp4' Does it ever skip then? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1103236 Title: Choppy and pixelated video on Macbook Air 5,1.

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.
