Hi Bill,

I'm a intrigued that you seem unaware of the problems given your previous post regarding Parhelia cards.

The reason for specifying a lack of support for the Parhelia cards was due to many customer reports last year indicating problems using them in conjunction with DeckLink cards which did not occur with either NVIDIA or ATI cards. One of the more common reports related to black flashing on the output of DeckLink cards which went away (in most cases) when another card was used. There are other reasons why you might see black flashing including lack of PCI bandwidth or genlock issues. However there certainly have been significant problems in the past and we wished to avoid those. It is possible newer cards or drivers work in harmony with DeckLink cards but I'm not aware of any recent testing of the problem so I couldn't say for sure either way if the problem remains or if you can use the Parhelia cards reliably with DeckLink cards.
