I've recently been given an XCLAIM Video player(TV tuner), the VR 128 series-it's a few years old I might add, and I was wondering if this device is even campatible with my machine, an iMac. The tuner is MAC OS ready, but I don't know if my iMac, one of the original models, needs a video card or already has one. And I don't believe I can install one if I need one. Many thanks to those who repsond.
