New issue 484 by google....@cefn.com: Video playback is broken on both
Ubuntu Karmic and Lucid, unbearably choppy visuals and sound
http://code.google.com/p/pyglet/issues/detail?id=484

What steps will reproduce the problem?

I have the latest Ubuntu Lucid Lynx desktop on a Dell 1525, but have also
tested previously on a Lenovo T400 with Karmic with the same results. One
common factor could be an Intel video chipset.

1. Launch the video example program like...
python video.py tada.avi
...using the tada.avi test video distributed with Bruce the presentation
tool.

2. Observe frame refresh rates of maybe one every 5 seconds, and sound
broken up into 200ms chunks with 1000ms spaces in between. There are no
errors logged to the console.

3. Try installing newer avbin, newer ffmpeg, newer pyglet, newer Intel xorg
drivers (2.11). None of these have any impact
