I'm trying to find a TV tuner PCIe Card for my mac pro with hardly any luck. The one's I have found don't say anything about being Mac compatible and I don't wanna get something that doesn't work. I also think getting the PCIe Card would be better than getting a USB device. Any thoughts on this? Is there a better place to search for Mac-Compatible PCIe Cards? If I HAVE to get a USB device, then I guess I will... but, why have another port being used when I could just install a simple PCIe card. Any help would be appreciated. Oh, and the Mac Pros ONLY have PCIe slots right? No regular PCI slots? This is my first Pro desktop computer so I'm unsure about expandability.
