Re: Odd stutter/hiccup issue with video on 190.X
I haven't upgraded to Ubungo 9.10 yet, but I do know in all previous versions there is a nasty bug in the Gnome environment where silly gnome-screensaver continuously polls and hammers on the system which causes video playback to stutter. "killall gnome-screensaver" and see if that helps. Also, you might have some widgets running which are set to poll the system too fast. Stuff like CPU monitors, systems monitors, temp monitors, etc, get rid of this stuff or set it's polling rate to every 30 seconds or something like that. Try running top in a terminal when you see the stuttering and see if you can catch the offender.
