I edit video on a new Mac Pro with Final Cut Express HD. While firewire is great for my DVCAM deck, I need to input and output other video/audio sources into the Mac w/o using firewire. With Final Cut Pro, there is no problem: you simply use one of the many AJA products that are designed for the Mac Pro. However, they don't work with Final Cut Express. Is there an external device or a PCIe card that will allow video/audio to be inputted/outputted to/from the Mac Pro when using FC Express HD??
