I've been using a KWorld 110 with BTV for a couple of years but I don't use the OTA HDTV function because the experience has been so problematic. I just noticed that KWorld now has a 115 card that supports QAM but ony with ArcSoft's TotalMedia. See here:

I guess I'm wondering if ArcSoft can support QAM why BTV can't support QAM? It seems like BTV is supporting QAM in HDHR; so what is different about the KWorld card or the Fusion card, for that matter?
