Just my 2 cents, but I think those guys you talked to are right. I've
done extensive research on the web to find out whether it was possible
to do decent video capture with a 770 TP and I think that's definitely
impossible. I mean definitely.
IBM remains very vague on the subject, I think in order not to
acknowledge the fact that this "video capture" feature just does not
work (except for still images ot crummy video conferencing...).
I once read a post by someone who seemed very knowledgeable in TP
hardware which said that the Video Adapters hardware could do decent
capture but that IBM would never write the appropriate drivers because
there's no market worth such an investment.

That's the only solution. BUT someone recently posted something about
IBM's Docking Stations having *poor* PCI performance, which would be a
major nuisance for video capture and editing.
I think you should buy a desktop, high end SCSI hard drives and
controler and a real video capture card. There's just no othr way to do
what you want to do.
Good luck.
PS : Greg Langham's post could be of some interest to you too :
>I have a Selectadock III with a Selectabase 770 and a 9549-8AU 770Z. I >have
installed a Number 9 PCI Digital video card which is part of the Silicon
Graphics 17.3" flat panel bundle. (Which, by the way, is the only
monitor I
have ever seen which beats the 13.7" LCD of the 770).
My question is this: When I connect my 770 to the dock, then boot, the
machine produces no display on the pci card. It waits about 10 seconds,
beeps, then automatically reboots. At this point, I get a display on
the
pci adapter and everything is fine.
Now, when I undock and turn my machine on, I get the standard power on
display. Again, it goes for about 10 seconds just sitting there, beeps
once,
turns off the LCD, then comes back up and boots. If I reboot the machine
while still undocked, the machine doesn't go through this procedure.
I'm guessing that the machine is noticing a change in its configuration
and
must reconfigure something in the BIOS.
Now the problem is this: If I boot connected to the dock after having
been
undocked, everything works fine; however, If I boot twice in a row when
connected to the dock, the machine hangs and never even produces a
display
at the second boot. The solution is to pull the machine out of the
dock,
boot, turn it off, and plug it back into the dock. Seems a bit clumsy.
I have noticed others using pci video (voodoo cards, etc.) and was
wondering
if this is just a characteristic, or do I have something configured
wrong?
