Thanks! That was the solution to problem why InitVCD and VCDOpenIntf
were not called. I basically changed all occurrences of "vcdplay" to
"vcdx."

Now I'm just getting a Segmentation fault inside input_ClockManageRef
(file src/input/input_clock.c) called from DemuxPS 
(file modules/demux/mpeg/system.c) here:

        case 0x1BA: /* PACK_START_CODE */
          ....
                /* Call the pace control. */
                input_ClockManageRef( p_input,
                                      p_input->stream.p_selected_program,
                                      scr_time );

It seems that p_input->stream.p_selected program is NULL. The "then"
part of the below "if" inside input_ClockManagerRef really does nothing
(since it is the same as what p_pgrm was set to on the call):

void input_ClockManageRef( input_thread_t * p_input,
                           pgrm_descriptor_t * p_pgrm, mtime_t i_clock )
{
    /* take selected program if none specified */
    if( !p_pgrm )
    {
        p_pgrm = p_input->stream.p_selected_program;
    }

so we die in trying to dereference p_pgrm. 

    if( ( p_pgrm->i_synchro_state != SYNCHRO_OK ) ||

A VCD doesn't have multiple angles like a DVD might. Where/How is
pp_selected_program supposed to get set? It isn't mentioned in either of
the vlc VCD plugins.

Thanks.
