On a default install with a new and powerful system, I had the same video stuttering issues--particularly with HD. I did find, however, that using VLC and just the CPU to decode the video looked just fine. So, there was something in Unity not playing well with the GPU/driver.
I found two ways to fix my video stuttering problem in Natty: 1. Log in to Ubuntu Classic This fixed pretty much all of my video problems. 2.Upgrade to the 275 nvidia driver. This made the stuttering under unity much less severe and only noticeable if I try really hard to see it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/780007 Title: [Natty] Stuttering video playback To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/780007/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
