HOW TO MAKE CU-SEEME WORK WITH THE OLD VIDEOBLASTER AND WINDOWS 95

(At least how I did it :-)

1) First of all, make sure that you actually have the correct videoblaster
for this how-2. The videoblaster I'm talking about is the very old one, made
around 1992 I think, with NO model number (It seems all the new ones have).
This one simply is called Creative Labs VideoBlaster. THIS HOW-2 MIGHT OF
COURSE ALSO WORK FOR OTHER VIDEOBLASTERS, even other brands of video capture
boards, but I cannot verify that.

2) Make the original Video Blaster Software work.
For now, stick to DOS. Run the program called VBSETENV.EXE to make sure that
your machine can talk to the card. IT'S IMPORTANT TO KNOW THAT IF YOU HAVE A
MACHINE WITH 16MB OR MORE MEMORY YOU MOST LIKELY WILL NEED TO USE A BIOS
OPTION CALLED 15-16MB MEMORY HOLE TO MAKE THIS WORK (OR REMOVE ENOUGH MEMORY
SO THAT YOU HAVE UNDER 15MB OF RAM) The reason is that *this* VideoBlaster
uses the 15MB area for a buffer. My motherboard has 16MB of RAM, and I *had*
to use my very nice 15-16MB Memory Hole option. (Thanks to AMI!) Anyway, if
the VBSETENV.EXE program tells you that everything is OK, proceed to 3). If
not, you'll probably have to move your other cards IRQ's or IOaddresses
around to squeeze in the VideoBlaster.

3) Run the VBLSTDRV.COM driver and then simply run the VID_ON.BAT file
(remember to stick to DOS for now - NOT a DOS window - boot the machine with
'Command Prompt Only') and the video image should appear somewhere on your
screen.

If it doesn't, check your drivers/programs versions. Mine are:

Filename Size Date
vblstdrv.com 13606 6-12-92
vbset.exe 13799 6-03-92

These are the two files you need to get the video image (in DOS)

4) Now for Windows95 (perhaps also other Windows versions)
Add the VBLSTDRV.COM to your AUTOEXEC.BAT, and make sure that VBSETENV.EXE
added a line looking something like:

SET VIDEOBLST=C:\VBLASTER A2AD6 I12

Boot the machine in Windows95 and open a MS-DOS prompt. Maximize the Window
and run VID_ON.BAT. If the video image appears (it really should) - good! If
it doesn't something Windows95 loads might conflict with the VideoBlaster
card. I had a Plug'nPlay card which Windows95 changed the settings of to
conflict. Change that in the Windows Add-Hardware-Wizard thing.

5) Now for the original VideoBlaster Windows software. The VBWSETUP.EXE
program let's you allign the video image in Windows. STOP! If you're using
any other resolution that 640x480, I can't tell you what to do. My
Videoblaster does not work at any other resolution (yet). Both 16 and 256
colors work. There is an 800x600 option in the setup program, which appears
to have no function :-)
Anyway, first of all you have to install some drivers - MANUALLY!

In the SYSTEM.INI file the following should appear:

[drivers]
msvideo=vblaster.drv
VIDC.cyuv=vblaster.drv

[MCI]
Overlay=mcivblst.drv

The files you need are: (Mine are:)
Filename Size Date
vblaster.drv 38282 1-13-93
mcivblst.drv 9152 6-19-92
pcvideo.dll 61504 11-22-92

These files should be in the \WINDOWS\SYSTEM directory, and nowhere else
(someone said)

Restart Windows and start the VBWSETUP.EXE. If in 640x480 resolution, a
video image should appear. This is probably the most critical part, and the
part where I have least to offer. This worked for me the first time :-)

Allign the video image and save the configuration. Opening the VIDEOKIT.EXE
program should give you an image that completely fills the window.

6) Now for CU-SeeMe. I've used CU-SeeMe W0.70b1. Install it according to the
docs (which basically means copy everything into one directory, MOVE
MSVIDEO.DLL to \WINDOWS\SYSTEM) STOP! If you have ANY version of MS Video
for Windows installed and working, it's *probably* better to remove the
MSVIDEO.DLL that came with CU-SeeMe and stick to the one that came with MS-VFW!

The CU-SeeMe docs says that a very important thing is that SYSTEM.INI should
have an msvideo=<videoblaster.driver> entry under the [Drivers] heading.
This is *VERY* important - BUT as I found, not enough.

7) Starting CU-SeeMe now should give you the Video Format and Video Source
options on the File menu. If it doesn't RECHECK EVERYTHING!

8) Video Format. The ONLY video format working with this setup is

8 bit Palettized
160x120 (1/4) image

9) Yet to try

I've not managed to get it to work in higher resolutions, different video
sources (my Vblaster has 3 ports), but in CU-SeeMe only one of them works.

Hope this has given you at least a hint on what to try next. It really is
difficult to get CU-SeeMe working on a PC, but if it was just Plug'n Play,
it would have been as interesting as playing an adventrue reading from a
WalkThrough.
