On my win 7 64 bit new installation of CS4 my Premier or OnLocation would not control my capture video devices.
The solution turned out to be simple but not something I found on any help forum.
Go to the device manager and open the IEEE 1395 Bus host controllers. It probably has some manufacture device drive listed. Right click and select update driver software, then select browse my computer and install drivers manually. You should get a selection of drivers. Select OHCI compliment host controller (legacy) and this will install, cause a re-start and should then render the capture device fully working.
