With mplayer? I think he's referring to the "Xvideo Extension" ouput of mplayer.
To use the HW acceleration the card need to support the YUY2 packed and YV12
planar pixel format, and with similar configuration here (kernel 2.4.5 XFree86
4.0.3-4 and same libglide3), the output of xvinfo is:

X-Video Extension version 2.2
screen #0
  Adaptor #0: "3dfx Accelerated Video Engine"
    number of ports: 1
    port base: 74
    operations supported: PutImage
    supported visuals:
      depth 16, visualID 0x23

       ...

      depth 16, visualID 0x32
    no port attributes defined
    maximum XvImage size: 1024 x 0
    Number of image formats: 2
      id: 0x32315659 (YV12)
        guid: 59563132-0000-0010-8000-00aa00389b71
        bits per pixel: 12
        number of planes: 3
        type: YUV (planar)
      id: 0x30323449 (I420)
        guid: 49343230-0000-0010-8000-00aa00389b71
        bits per pixel: 12
        number of planes: 3
        type: YUV (planar)

so not YUY2 packed...

Any hints?
