I had been using VDPAU fine for a while and then a month or two ago I
noticed minor tearing in a horizontal band across the screen similar
to what you describe. It was driving me crazy. I finally saw another
post on the list that mentioned adding this to your xorg.conf:

Section "Extensions"
    Option         "Composite" "Disable"
EndSection

I had that in my xorg.conf in the past but somewhere along the line it
got removed by me or some automated update. That fixed things for me.
Playback is flawless again now.
