I've figured out a workaround or a means of getting the player to play the media entry. The media entry / link above now works... Please feel free to test it. (The first 4 seconds of the video is just a black screen...)
The reason the media entry won't play / the player displays "No source video was found" appears to be because we had associated a Category with the entry. Once I remove the Category (and wait several minutes... I guess something is cached??) the video plays correctly.
If I re-add the Category (again, wait several minutes), the player fails to play the media entry again.
We really have the business requirement of using Categories. Do you have any idea why having a category assigned would cause the player to fail?
Thanks in advance,
