Yes, I realized that after I posted my message.  Here are the new values
after skipping the program header.  (I also added the .pw and .ph to the
list, they look correct).

Pixel Mode: 2
   Pixel X: 513
   Pixel Y: 0
   Pixel W: 320
   Pixel H: 240
   Pixel *: 80110014
   CLUT CX: 17
   CLUT CY: 4294963200
   CLUT CW: 8192
   CLUT CH: 0
    CLUT *: 2000

As you can see, the pixel mode is now 2 instead of the 16 I got before. 
The pixel width and height are perfect at 320 and 240.  The address of the
pixel data of 80110014 seems ok.  But the rest of the numbers still don't
make any sense.  I ran this exact same program with the MASCOTS2.TIM (those
little cartoon girlies from the 2D demos) and this is what I got:

Pixel Mode: 9
   Pixel X: 640
   Pixel Y: 320
   Pixel W: 102
   Pixel H: 120
   Pixel *: 80110220
   CLUT CX: 0
   CLUT CY: 481
   CLUT CW: 256
   CLUT CH: 1
    CLUT *: 80110014

Which looks perfect to me (except maybe the pixel mode of 9?).  So maybe
something is wrong with my PICTURE?  I looked into this possibility and
wrong this small program:

#include <libps.h>
#include "d:\yaroze\lib\pad.h"

#define PICTURE 0x80110000

void main(void)
{
   GsIMAGE Image;
   RECT Rect;
   GsOT OT[2];
   GsOT_TAG OTTags[2][2];
   PACKET Packet[2][24];
   int Buffer;

   PadInit();
   GsInitGraph(320,240,4,0,0);
   GsDefDispBuff(0,0,0,240);
   GsGetTimInfo((u_long *)(PICTURE+1),&Image);

   OT[0].length=1; 
   OT[0].org=OTTags[0];    
   OT[1].length=1;
   OT[1].org=OTTags[1];
   GsClearOt(0,0,&OT[0]);
   GsClearOt(0,0,&OT[1]);

   Rect.x = 0;
   Rect.y = 0;
   Rect.w = 320;
   Rect.h = 240;
   LoadImage(&Rect,Image.pixel);
   Rect.y = 240;
   LoadImage(&Rect,Image.pixel);

   while(PadRead(1) != PadSelect)
   {
      Buffer = GsGetActiveBuff();
      GsSetWorkBase((PACKET *)Packet[Buffer]);
      GsClearOt(0,0,&OT[Buffer]);
      DrawSync(0);
      VSync(0);
      GsSwapDispBuff();
      GsDrawOt(&OT[Buffer]);
   }
}

And it displays the PICTURE 100% perfectly.  So, what's going on?
(The picture by the way is the WIPEOUT title screen found on the
"Playstation Picks" demo disk that originally came with the PSX.)

Help!

Nelson.
