There's another document:

http://stnsoft.com/DVD/spu.html

It's written independently from the other, so it calls things
by different names.  This one is from a vendor of DVD authoring
software, so I think it is quite reliable.  To quote from that
page:

    00 - FSTA_DSP - Forced Start Display, no arguments 
    01 - STA_DSP - Start Display, no arguments

I think that's pretty clear.

Best regards
