I have been struggling for the past two days to get my new 8700 desktop to recognize my AverMedia A188 or Hauppauge 1800 tuner cards. Both work in my old XPS 420, but neither one is recognized in Win 7 or 8 on the 8700. I read a post on this forum that there are numerous PCIe cards that are not detected. I have never had this problem with my old reliable XPS 420. Out of desperation, I even tried updating the firmware from A03 to A04 with no luck. Is there a list somewhere on what tuners are compatible on the 8700?
