On Twitter when trying to play videos, I get the error 'The media could not be played'. I can download the video using plugin Video Download Helper and play it fine from my pc.

On Howcast when clicking on a video, I see one of those 'Activate Adobe Flash' popups for a split second and then disappears. The video then just keeps on loading with the round loading circle going round and round. On other sites when the 'Activate Adobe Flash' pops up it stays there and allows me to activate Flash and then the video plays. But not on Howcast.com

Confirmed Video does not play in Firefox. No problem with Win IE.

My download manager shows the clip is there, and I can Download it. Note: Right-click on player does not display type of player being used. Flash, HTML5 . . . . .

Tried   Howcast.com   and it plays just fine for me.
