When recording sound is OK but video is black :(

I have seen that JMR 7.0.2.1 was suppose to fix problem but does not work on my system.

Jaksta Media Recorder Review
May be thisalso explains that about 10 days ago it worked on my Windows 10?
Here is adescription of how it worked:
I wastrying to record TV from my ISP @ https://chaines-tv.orange.fron my Win 10 system. Therefore, after clicking on the DVR button of JMR, abrowser window opened and I could select the channel to record then I clickedon record button. To my surprise the browser window closed (normal) but a new largeindependent window opened (?) displaying the recorded channel. After stopping therecording, this window was closed and the image / sound where recordedcorrectly. As I said this behavior is now broken and DVR only record sound but witha black image.
Meanwhileto work around this problem I run JMR on a Windows 8.1 system under VMWare. Itworks but the behavior is different: after clicking on the record button, thebrowser window close and a small window inside the left panel of JMR open atthe bottom and display the recorded channel (this is the behavior I am usedto).
I reallylike the behavior with the large windows as it is much more easy to follow theprogress of the recorded windows.
Questions:
- Was this large windows opened by JMR?
- Was this new behavior of the “recording windows” introduced in 7.0.2.1?
- Was this behavior removed in 7.0.2.9?
- Will this be the behavior (having a large independent window) when JMR is finally fixed?
- Any plan tobe able to hear sound when recording (important improvement)?

IMPORTANT INFORMATION
Guess what:after writing the above description I have decided to test several previously releasedversions of JMR and here is what I found:
- JMR 7.0.2.1 has broken recording
- JMR 7.0.2.4 Recording is working fine with separate windows displayed
- JMR 7.0.2.9 has broken recording
Here is amore detailed description of the behavior in 7.0.2.4
As mentionedin previous post, a “large window” opens during recording. This window is stuckin the upper left corner of the desktop and cannot be moved. A “player window”is located inside the large window, and it is possible to move this playerwindow inside. In that case the “player window” is clipped inside the “largewindow” and the background is black. The recorded video is simultaneously displayedinside the left JMR panel.
I haveattached a picture of my desktop during recording (red arrow points to “largewindow”, blue arrow to “player window”, and green arrow to JMR player window)
It often happensthat the large windows disappear after sometimes, however the recordingcontinue correctly and the recorded video is still displayed in JMR left pane.
This may beinteresting to developers. They almost fixed the problem with 7.0.2.4 eventhough behavior is still unstable. Unfortunately 7.0.2.9 breaks recording again

Thanks for your investigation/feedback. Very helpful.
So two things have hit at the same time.
Chrome 76 doesnt allow the UI to be controlled in the same manner as we currently do, and a windows update has changed some of the undocumented API calls we use.
You can fix the window opening on screen by doing a full reinstall (deleting your library and settings) OR by deleting the file C:Users<your username>AppDataLocalJaksta Media Recorder 7JakstaDVRvd.18362.generated.dll.
This auto generated file will be regenerated with the new undocumented api calls we use when the DVR starts recording.
Ive changed the installer to remove the autogenerated file on and upgrade install, but the Chrome changes Im still working on. DVR will then work but you will see the title bar in the DRV recording.
Ive updated the KB to reflect the current state of play: https://www.jaksta.com/support/windows/kb/windows-10-1809-dvr-recordings-are-blankblack-videos-6000221913

Problemwith DVR browser
I did theabove tests by recording Netflix video. The reason is that the DVR browserseems to always work correctly with Netflix.
But when Itest the DVR Browser on TV from my ISP, in most cases the Web page is not displayedcorrectly. For example I specify the https://chaines-tv.orange.fraddress and click the DV record button, the DVR browser window open at https://chaines-tv.orange.fr/#live/homewhich is a normal redirection. For a very short time the web page is displayed correctlybut rapidly the content of the windows turns black and after 30 seconds thewindow is closed and the recording (of a black video) is completed.
As already mentionedit would be nice to the sound of the recorded video, because it is sometimesdifficult to know the status of the recording on a very small window.
