Not only is it WinTV that fails, it is all the various dtv front ends that I have tried.
What's frustrating about this kind of situation is that we never know if Microsoft or Hauppauge or any other stakeholder is working on it. As far as I am aware, Microsoft hasn't even recognised the problem's existence. I put in a ticket at Happuaauge some 2 weeks ago but still haven't heard back from them.
I agree, it just won't do.
