Work for what? It may be able to recieve TV, but that doesn't make it a PVR solution. If you try and record, (with your current system), you'll probably not get much over 320x240, with huffyuv or mjpeg (if the hard drive and CPU are fast enough to write that much info, that quickly). You will probably want a hardware mpeg-2 encoding capture card (the Hauppauge one's mentioned in your other posts), which doesn't rely on your CPU to do any work.
