side note. there was a special cable used to bridge 2 seperate cards together so you would have 4 timed video sources.
there was also a daughter card to enable the svideo out.
I think there was also another option that let you use external sync - I can't remember.
I used mine with the video toaster as 1 unit.
The breakout box will let you put svideo or composite in, but you can only get svideo out if you have the daughter card.
