[MIKEROPHONICS]

sorry George if you thought I was being short, I was out and about on my phone and had a deadline to get my son off to a scout expedition.

If you have thunderbolt - get the IOXT (which is a Kona in a thunderbolt box), if not then the KonaLHi (I think the more affordable Kona LHe plus is SDI output only).

Much better performance and accuracy than any BM solution - and the drivers just work. You can just update drivers when they come out, and not have all the disasters of life in the Blackmagic Lane
