I think the only way you would be able to do this is by having a
timer -
i.e.

static short iTimer=0;
static short iLast=-1;

if( PadStatus&PADdown)
{
    printf("You just pressed the D-PAD: DOWN\n");
    if( iLast == -1 )
    {
         iLast   = iTimer;
        printf("First press\n");
    }
    else
    {
        // take it that we want it to be pressed twice within 5 updates
        // you will have to alter this according to how fast you need to do
        // the double press
        if( iTimer - iLast < 5 )
        {
            AnimateCrouch();
            iTimer = 0;
            iLast = -1;
        }
    }
}

if( iLast != -1 ) iTimer++;


This should help. If not just drop me an email
