So I was successfully burning DVDs from File Explorer (Manage > Finish burning) until installing Insider Preview. Then trying to burn a DVD failed and resulted in the attached message. So I used a third party software (ImgBurn) and successfully burned the same DVD, using the same Audio_TS and Video_TS folders as before. Anyone has the same problem?
