How often are the software support packages updated?
The software for the PCI DV series of products (Digital video) boards is typically updated 3-4 times a year, as support for new cameras is added. Software for other boards is updated somewhat less frequently but still at least a couple of times a year. Best bet is to check the version associated with the software in question against the contents of the version file in your installed package, to find out if you have the current release.
