Ok, PC community, I've tried the VideoLogic Captivator board (not the Pro/TV
board - $ 99.00 directly from VideoLogic - 800-578-5644), with CU-SeeMe,
Microsoft Video for Windows 1.0 and 1.1, and VideoLogic's VideoSnap application,
on the following platforms, all without a single installation or usage problem
so far:

Packard Bell Legend 2000, 486/25, 8mb Memory, Windows for Workgroups 3.11,
Trumpet 2.0B

Digital 466D2LP, 486/66, 16mb memory, Windows for Workgroups 3.11, Microsoft's
Wolverine IP stack

Digital 466D2LP, 486/66, 16mb memory, Windows95 final beta, Windows95 IP stack

Digital 450D2MT, 486/50, 32mb memory, Windows for Workgroups 3.11, Microsoft's
Wolverine IP stack

If anyone wants further information on the above configurations (e.g. - what
BIOS are you running, what's your video setup, ...), drop me an e-line.

A couple of P.S.'s (one related to this subject, the other not):

1) For those of you on PC's anxious to get started using CU-SeeMe both as
a sender and receiver, keep in mind that Connectix is due to begin shipping
their QuickCam for the PC at the end of this month. The QuickCam is a
Digital Camera which captures in black and white, plugs directly into a
16550 UART serial port, and has a proven history with CU-SeeMe on the Mac.
No need for a capture board, surgery on your PC to install said board, or a
separate, sometimes expensive video source (e.g. - CamCorder). The MSRP on
the QuickCam is $ 149, with a likely retail price of ~ $ 100 - 130.
Unless you really have to get going with CU-SeeMe now, I'd wait until
the QuickCam for the PC ships, and someone on this list (I plan on buying a
couple :-) buys, tests, and reports the results of using the QuickCam for
the PC with CU-SeeMe for the PC.

2) Off the main subject, every time I've seen discussions on this list about how
CU-SeeMe will operate over a modem at various speeds, the speeds discussed
have been 9,600, 14,400, and 28,800. Is anyone out there aware that if
you've got a 14,400 V.32 or 28,800 V.34 or V.FC modem, you can really
do 57,600 max (in the case of the 14,400 modem) and 115,200 max (in the
case of the of the 28,800) by using the compression capabilities of the modem
(e.g. - in the case of the V.34/V.FC modem being used with Trumpet, simply
tell Trumpet to operate at a baud rate of 115,200). This of course presumes
that the receiving modem can handle the same modem protocols as the sender
(and the phone connection isn't noisy :-(. In the case of the V.34/V.FC modem,
that's getting pretty close to 2 channels on a T1 circuit (128 KBS). The only
part I'm not sure about is whether the compression capabilities of the modem
make much of a difference when CU-SeeMe's UDP data stream is involved ? Can
someone shed some light on that question.

Regards,

John Faherty
