Did you tried this:

code:

---

FUNCTION fn_switch_video_to_8_32_1();

STRING string_video_control[40];
STRING string_succeeded_8_32_1 = "Video_switch 8, 32, 1 succeeded!"
STRING string_failed_8_32_1 = "Video_switch 8, 32, 1  failed!"

TEXT text_show_video_success
{
LAYER 2;
POS_X = 100;
POS_Y = 100;
FONT ....;  //give a font
STRING string_video_control;
FLAGS VISIBLE;
}

FUNCTION fn_switch_video_to_8_32_1()
{
IF (0 != video_switch( 8, 32, 1))
  {
  str_cpy (string_video_control, string_succeeded_8_32_1);
  }
ELSE
{
  str_cpy (string_video_control, string_failed_8_32_1);
}
}

ON_A fn_switch_video();

---

Does it also give a error message? Maybe not! I didnt tried it, but hoping I could help a bit...

Note: If your viedo card is too weak, try it in the window mode (video_switch( 8, 32, 2). Good success!!
