cannot play media, after editing in timeline

Hi there

I hope you can help me out here, I was working since 2 month now with DR 14.0. I have some media in media tab, and a multicam timeline.

Yesterday something strange happend: First I could play the media in media tab just fine. Afterwards I moved to my multicam timeline, I played the timeline via play button, this has worked for two seconds, afterwards only the audio played further, but the image stopped.

If I then go back to the media tab, I only see a black screen instead of the media. Playing of the media is not possible any longer. Did I something wrong? I just have updated to 14.2 (same issue occurs). It also cannot be an hardware topic, as all has worked fine for about 2 month. However I have a i7 Laptop with 950 GPU.

Maybe you can help with an answer to following generic question:

What should I investigate, when I cannot play media in media tab? This only happens, If I was in the multicam timeline, and if I tried to playback that multicam timeline... Attached screenshot for reference.

Thanks in advance for tips.

Best,
Steve

Do you have video scopes turned on? or data burn in?
if so can you turn these off and test.

I'm not having any checkbox ticket unter "data burn in". How to turn them off completely?
I can see video scopes in color tab. How can I turn off them? Thanks.
Generelly I'm not working in the color tab at all, to I don't expect the issue to be there

Expect what you dont expect is safer.

In the color page, RHS there are icons on the toolbar above scopes.. you can select another.

Finally I went for the hard solution. I just installed Windows 10 completely new.
Now i have a clean DR14.2, and it is working very well
