Help please.  I'm trying to write the simplest Hello World program in  
TookBook v1.53 with MCI Extensions running under Multimedia Windows 3.1.
I want to write a little script to wake up my Pioneer LD-V8000 videodisc player
and play a disc using the New Media Graphics Super Video Windows Overlay card
that I've got installed in my Zenith 386/20.  

When we installed the overlay card in Windows, we used Setup, Drivers
option, and did a regular install off the floppy disk which contained
the oemsetup.inf & the driver for the card, which is svwmci.drv.  The
svwmmi driver in not configurable from Setup, but from its own software
configuration program, vconfig.exe.  In vconfig we specified as a 
videodisc driver mcivpion.drv, an mci driver for the
Pioneer which we obtained elsewhere.  (We also tried specifying
pnr4200.drv, the driver that came with the overlay card.  Didn't
seem right to specify a non-mci driver though if we wanted to use
the mci hooks.) We set it for Source=laserdisc, com1 port, and 9600
baud, all of which is as it should be.

Under [mci] in system.ini we've got overlay=svwmci.drv, and
videodisc=mcivpion.drv com1: 9600.  The overlay entry was created
by Setup, the videodisc entry we entered by hand due to having no
oemsetup.inf for the Pioneer mci driver.

I'm using the tbkMCI function to call various commands from the mci
command set in ToolBook.  I'm using sysERRORnumber after each mci
command call to check errors.  I can get it to say that it is opening
the videodisc or the overlay, and it does wake up the videodisc some
of the time.  Most of the time though, immediately after I

get tbkMCI("open videodisc shareable","")

I get a message saying Operation failed.  Improper laserdisc DLL for
Source1 overlay.

There's a video.ini file which has under [Sources] Source1=Laserdisc.
And under [Source1] it has Signal-NTSC, Active=YES, Control=COM1:, and
DLL=mcivpion.drv.

Is anybody kind enough to look through all this & offer some advice?
It should not be that hard to make the overlay board show the video.
New Media Graphics is trying to help but they are not a lot of help.
