thanks, Derek.
but what i don't understand is this.
if the Spectra8 currently uses WDM drivers in Windows...
VIC relies on VFW type drivers. that's what the problem is/was with the
newer WDM driver Winnov Videum cards and VIC.
i'm missing something.

Hi,
Having installed a Spectra8 after using a WinTV 150PVR, I can tell
you it's *very easy* to get going. Yes, each input installs a driver
individually (4 goes round the 'found new hardware' wizard - yawn, but
once it's done it's done). After that it just works like 4 individual
capture cards. As mentioned before, the inherent problem with VIC not
being able to differentiate between the sources and 'colliding' over
what input to use still remains, but that's Windows thing and happens
any time there is more than one capture device. You just have to select
the 'other' source(s), whatever they may be, when the window prompts you
and all sources will come up nicely.
Spectra8 cards, being 4 BT878 chips, would work nicely under Linux
and not suffer from that problem (they'd just be /dev/video0, /dev/video1
etc.), although I have not personally tested it.

this has been covered in various ways at various times. but i've got
a new question on this subject.
we had a problem with the last Winnov Videum card we spec'd for another
institution because before they purchased the card the Videum been upgraded
to WDM drivers. while the VFW drivers would make it work right for AG,
this
other institution needed to use the software that came with the capture
card.
i've noticed quite a few posts by people successfully using the Spectra8
4 input card. so i've now come to the point of replacing that Winnov
Videum with something that will cover all the needs of our collaborators;
proprietary capture software and AG.
i'm looking at a web page with Spectra8 specifications. i'm very, very
surprised to see, "... each frame grabber channel has it's own WDM driver,
allowing you to capture from 4 individual video channels."
now i'm really confused. is the WDM driver relatively recent for the
Spectra8? it must be... or how have people made it work well with AG...
any insights would be greatly appreciated.
