You can check the adaptor info by running "xvinfo", which will output
info like:

screen #0
  Adaptor #0: "Textured Video"
    number of ports: 16
    port base: 63
    operations supported: PutImage
    supported visuals:
      depth 24, visualID 0x21
    number of attributes: 2
      "XV_BRIGHTNESS" (range -128 to 127)
              client settable attribute
              client gettable attribute (current value is 0)

For the mplayer, you can specify it to use textured video by using
mplayer -vo xv port=63 VIDEO_FILE  #you get the port number as xvinfo
