Chrome will not play certain flash videos

My chrome is set to use pepper flash (as is the default, I do not have any other flash player installed).

I am encountering a strange error where some flash files do not play. As an example the two videos on the top of this page do not play. I've seen .swf and .mp4 formats play for me and I have confirmed that two .flv videos failed loading.

How do I troubleshoot and fix this issue?

Update: I reinstalled chrome and found that on the fresh reinstall, I could play the videos but as soon as I "synched" with my GMail account and it's settings, the videos would not play anymore. Resetting the settings to default did not seem to change a thing either. The videos do play in a Linux version of the browser on the same account though which is odd to say the least.

Solution 1:

I found the problem, I was running the HTTPS Everywhere Chrome (beta) extension. Turning it off solved the issue.

A workaround would be to disable the extension in incognito mode and run videos that won't play normally from an incognito mode window instead.
