I'm building a low-end knoppmyth system for my sister, and was thinking of putting a couple of these tuners in (they're $25 shipped, from newegg), but I was hoping to make sure they actually worked with knoppmyth first. It seems that a few people have had some difficulty with the SBT-TVFM cards from the same manufacturer, but these posts are also a little older. Has anyone had any success with either of these two cards?
