Comment 5 for bug 300785

Have you opened a 'terminal' window its like a 'command' window in Windows (try Applications menu, Accessories, Terminal - then try

gstreamer-properties (remember pressing the tab key does predictive text style)
click on video ouput (or something similar in the pop-up box)
under plugin select X Window System (no Xv)

then restart totem.

Also try the System menu, Administration and find the Hardware Drivers for a great little program to tweeak and optimise performance for your graphics card. I did that and suddenly found all the writing on my screen is a lot less blurry :)

Good luck and have fun :)
