I cannot watch Coursera's video lectures. What's wrong and must be fixed? I only see a black page and then nothing happens, no matter how long I wait. Should I change the setting or are some plugins needed?

What about other browsers, do they display the video ? – Ankit Mishra Dec 25 '12 at 5:44
You have click to play or something like that enabled? What does error console say? (Hit F12 to bring it up) – Sathya Dec 25 '12 at 7:00
@Sathya: It says "failed to load resource". – Gigili Dec 25 '12 at 10:50
@Lamb: I didn't try FireFox but Internet Explorer 8 doesn't even open that black page. It says "done, but with errors on page". – Gigili Dec 25 '12 at 11:11

Could be a connectivity problem. Posted screenshot shows that plug-in loads without a problem, but it cannot get the content to show. Also, you can try right-clicking in coursera video screens and choose "download video". By the way, what's your answer to Lamb's question?

Thank you, I didn't notice that it is possible to download the videos. – Gigili Dec 25 '12 at 11:11

Definitely not a connectivity problem; it's a Chrome problem. Numerous people - including me - have had this issue. A bug (at least one!) has been reported:

It looks like they're having trouble reproducing the problem; Additional data posted to this bug report may help get it solved!

I was not able to get any of the suggested work-arounds to fix the problem. Videos play fine in Firefox on my machine.
