Another video that JMR will not capture:
When I right-click on the errored capture, select Properties, and look under General tab, the Source field shows:
The URL originally visited was:
Instead of relying on auto mode to capture the video, I also tried entering the URL into the address bar in JMR. That worked. If I manually enter the URL for the web page with the video, JMR captures. If I rely on Auto mode, JMR fails. I immediately tried the URL in the web browser (after exiting the web browser, using CCleaner, and reload the web browser to make sure JMR would re-capture from the same web page), and the capture failed using Auto mode. Capture worked when I entered the URL into JMR to manually start the capture.
Seems a problem with Auto mode. Under Settings -> Internet Downloads, "Start automatic detection on start" is enabled, because I want JMR ready when it loads to capture wherever I happen to visit in the web browser.
Attached are the debug files.
Note: I am *not* using a VPN (unlike FelipeA that found his VPN was interferring with JMR).
