Andrew,
Ben’s recomendation of the MXO2 is a good one, but it does depend on your flavor of G5.
Please read the following from the Matrox MXO user Forum:
Hello
Designed to streamline editing workflow with Apple Final Cut Studio and Adobe Production Premium on MacBook Pros and Mac Pros, Matrox MXO2 provides broadcast-quality input/output, monitoring, and up/down/cross conversion.
The system requirements for the MXO2 are :
– Support on Apple Intel-based systems and the Leopard O/S (will not work on Tiger).
– On a laptop, the MXO2 requires to be plugged into the external express/34 slot found on all MBP.
– The MXO2 requires an internal x1 PCIe card on Apple towers. It cannot be connected to a PCI-X slot.
Therefore, the MXO2 will not be compatible with older G5 models.
Have a great day
