Comment 8 for bug 330712

@Akagi, the phenomena with horizontal lines in fast moving scenes of movies is called "tearing" and it's a known issue.

Good news is that for textured video which is played back using the "xv" technology the issue has been fixed in the intel 2.7 driver version. Unfortunately this driver has published very recently (after we put together drivers for ubuntu 9.04 for example) so jaunty still has version 2.6.3 of the intel driver. Note that this concerns only "textured xv video" and it's only for intel cards. In the next version of ubuntu we will ship version 2.7 of this driver (or a later version) but if you want to experiment with this yourself you can install the 2.7 driver on Ubuntu today using the X-Updates PPA ( https://edge.launchpad.net/~ubuntu-x-swat/+archive/x-updates/ ).
