Don't have any.

You should probably look into if there are any advanges to this before
time is expended on writing code for it.

Not curently.  Should not be to hard though.  It's just a matter of
implementing the functions that mpeg2_video/video_output.c uses.
More specificaly:

/* Should allocate and set up everyting. */
void display_init(int padded_width, int padded_height,
                  int picture_buffer_shmid,
                  char *picture_buffer_addr);
/* Called when the input resolution/size is about to change, 
 * display_init() will be called again after this. */
void display_reset(void);
/* Display one image. */
void display(yuv_image_t *current_image);
/* Poll for input / redraw events.  For now the code to do screen shoots 
 * and pass on the events to the input client is located here too (should
 * be changed). */
void display_poll(yuv_image_t *current_image);
/* Called upon program termination. */
void display_exit(void);

Some very small tweek of mpeg2_video/video_output.c might be needed too.  

When we have more output modes I guess some code to select and try
different ones would be in order too. That is not the case right
now though, so one would have to select at build time or make two
binaries and select at startup to begin with.

Yes and a hack to output directly to the frame buffer of Creator3D cards.

Nothing says that like code ;-)
