You get much better picture, but you need very speedy chips for it. While the analog mixing Hauppauge is using, has a cable from the VGA card to Hauppauge card, it mixes the VGA and the TV picture (inserts it into the VGA picture) and gives it out via the second connector on the Hauppauge card. > > Luigi > Ulf. ----------------------------------------------------------- Alameda Networks, Inc. | Ulf Zimmermann (ulf@Alameda.net) 1525 Pacific Avenue | Phone: (510)769-2936 Alameda, CA 94501 | Fax : (510)521-5073
