Never mind, it looks as if you have a SiS video card. The SiS driver has not received much work for a while now and it seems unlikely that it ever will. You could try filing a bug upstream at https://bugs.freedesktop.org/ and attach your XorgLog.txt and GstreamerVersions.txt there, but your best bet would be to add a discrete video card to your system (or replace the existing SiS discrete video card). Even if you have an AGP system you should still be able to pick up an AGP card such as an ATI Radeon HD4650.
