Thank you, Fred28. DRM/TPM could be an issue. What I am trying to record streaming video from Cox Cable using their Contour app.
You are quite correct. It appears that Debut will indeed record other sources when Chrome is the browser.
What prompted me to ask the question is that the same content that Debut does not record in the Chrome browser, it records with no issue using the Firefox or Microsoft Edge browsers.
Thank you for your help. It looks like I might need to find a legacy version of Chrome . . .
