Thanks for this. It saves me a lot of messing about trying it out.
It's all very frustrating and such slow responses from the involved companies. Neither Hauppauge nor Microsoft have officially recognised the problem. We really are just pawns in their game, aren't we?
As Windows Insiders we are testing their software for them - I think it would be good if Microsoft acknowledged our service and responded to such matters identified in a way that gives us some idea as to what is going on.
