I'm deciding between purchasing one of these two capture cards. Does anyone have an opinion on either? I've heard (on newegg.com reviews) that the Asus card has an older model of the Philips Tuner (MK2) as compared to the Pixelview (MK3). I am also wondering if either of these tuners function with DScaler (video AND stereo audio). Any help would be GREATLY appreciated. Thanks.
