Take into consideration that Newer Black Magic products support only 3G SDI signals, the Red uses a 1.5G signal. So in order for the Hdlink or the BlackMagic 3D card the signal needs to be re-clocked to 3G. That will stop the 2 second drop outs, I bought the Redbyte 1-6 DA. I'm waiting to see how well it works. Currently I have to loop the signal through a monitor first... Which doesn't work well for 3D, but it does work for my Pci-e BlackMagic 3D card.
