ATI X550 Video Playback Spike

Well, one of chatters ask me how to solve a spiky video playback with ATI X550. Well, here is the solution:

• press ALT+F2
• type "gstreamer-properties"
• Go to Video Tabs
• Change Default Output Plugin Setting from AutoDetect to 'X Windows System(No Xv)'

Try play the video again and see if your playback still have spikes.
