You can install https://addons.opera.com/en/extensions/details/user-agent-007/?display=en in Opera and mask as another browser just to see if there's any difference.

Okay. That tells the error at least. Just not sure why so far.

Download Opera 48, launch it, click "options", set "install path" to a folder on your desktop, set "install for" to "standalone installation" and install. Try it in that Opera to test how it works. If it works the same, try disabling opera://flags/#media-windows-mf-demuxer to see if that makes a difference.

There's no option to turn that off in 49 I think, but just wanted to see if that makes a difference.

Opera uses system codecs and the Windows media stack to playback files, so it could be an issue specific to Win7 and the way the server sends that file where the demuxer has a fit. But, don't know.

You can modify the shortcut to Opera (will be to launcher.exe) and pass --media-windows-mf-demuxer=0 (or false or disabled or something). But, don't know if that'll work as it's possible that more than just the option in opera://flags was removed. You can try it at least.

Besides that, you should have enough info to create a simple test case for the one URL and file a report. You could mention this thread in the report too.
