Just a comment from the outfield ...
I think this is the area that can allow or disallow multi-input
video capture cards (e.g. the Winnov Videum 4400 which we use)
to work - which Matt Thorpe solved with a patch to the registry
(I'm talking Windows XP here, of course). Just a request that
some mechanism (setupvideo.py or registry hack) still allows this
sort of card to work under AG 2.2, as we don't anticipate moving
to inSors software, so can't use the 'inSors patch'. I'd heard
that what Matt had worked out for AG 2.1.2 didn't work in AG 2.2;
I think that comment was from Cindy.
