I use a Mobility X700 , fglrx 7.12 , xorg 7.2

As i read about the TexturedXrender I wanted to try it out. This lead to XV not working anymore as I had to enable Textured Video. below is how my Device section looks now in my xorg. Just Imagine it without the comments .

Section "Device"
        Identifier  "aticonfig-Device[0]"
        Driver      "fglrx"
        Option "XAANoOffscreenPixmaps"  "true"
        Option "OpenGLOverlay"          "off"
        Option "VideoOverlay"           "On"
#       Option "Textured2D"             "true"
#       Option "TexturedXrender"        "true"
#       Option "TexturedVideo"          "on"
        Option "AccelMethod"            "xaa"
with this config i have a nice clean Image when I watch a movie.
Xvinfo says :
X-Video Extension version 2.2
screen #0
  Adaptor #0: "ATI Radeon Video Overlay"
    number of ports: 1

If I enable Textured Video I get as adaptor ATI AVIVO ... ( sorry I was too lazy to restart the xserver to see the whole name ) and the image is all "blocky and tearing".

anyone know if there is a way to get a decend image quality with Textured video?
