I can confirm that: Other TV programs besides WinTV such as DVBViewer Pro also have the same problem. The bug is probably not in the software, but either in the TV-tuner driver from Hauppauge or in Windows 10 build 21277 itself.
Build 21277 - Hauppauge WinTV software stopped work

After upgrade Win 10 to the latest build, my Hauppauge Win-TV 10 software doesn't work. It will find the TV tuner (Hauppauge HVR-2200), but when I chose any channel, the screen is still black and I've got such info: "Er ror starting Live TV - Device in Use - Check Cortana is not using your Win-TV-HVR-2200 Serial:0". Which is strange, because I have no Cortana (in Polish Windows it's unavailable).
After reinstalling Win-TV 10 it can detect TV tuner, but when scanning channels can't find any except S-Video input (which is active, with cable TV STB connected to). When I chose in, I've got the same info as previously "Er ror starting Live TV - Device in Use - Check Cortana is not using your Win-TV-HVR-2200 Serial:0".

2020-12-29T13:24:38+00:00 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.
Please continue posting your findings as new software becomes available.

When come to Hauppauge card and other tuner the problem is with Windows 10 21277 it self because even manuel grahedit it useless.

2021-01-06T21:20:33+00:00 Thanks for the info. I am in communication with Hauppauge but they, so far, haven't been very helpful. They don't seem to understand the problem as I have stated despite sending a screenshot of this Microsoft thread.
How do we get Microsoft to listen? Have you provided feedback on the Insider Feedback? There appears to be no one supporting my post on the matter.
