Since the sources are not gen-locked, they could be (likely are)
running at very slightly different rates, so it seems probable
that you would drop (or duplicate) a frame every so often.
Dunno why that would be a problem unless you are trying to
analyze golf swings or something (in which case you likely
wouldn't be using this equipment). There are dropped/duplicate
frames happening all the time on the stuff we watch and 99.9%
of the time nobody notices (or cares).
I haven't seen a price for that thing yet. Care to share what
the cost was? If the price of INTC stock dosen't slump too
badly, I might buy one.
