DirectTV Does Not Work on my Computer

DTV sat service dropped support for streaming DVR recording to a computer/laptop long ago, the only thing you could stream are the channels available by logging into your DTV account.  The new partner maybe changing this in their new DTV app.

Thank you so much everyone for for your support. But after searching online, I came across this useful guide. They have suggested some useful methods and I followed some of them. First I disabled the browser extensions and then cleared the cookies and cache. After doing the methods perfectly, the problem got solved. Now when I am trying to connect it with my computer, it has no longer any issues while connecting.

DTV doesn't have any servers and flash player is no longer used so that is an old web page.
