Thunderbird 52.7 Windows 10 Pro x64. I get the BBC News RSS feed, but when I click on a video, most of the time I get a grey box and no video. Video in all other feeds play correctly. Searching Google for a solution mostly gives me links for Firefox, which doesn't help at all. Has anyone got a solution to this problem? I've tried updating video drivers, turning hardware acceleration on/off, but it makes no difference.
