By far, this one is the most updated one and works smoothly.
The installation, as well as every upgrade, is really simple.
The module interface allows literally to configure everything (in fact, there is a final open field for flashvars).
But the thing I appreciate most is the support team. I've had only a few questions and they have been answered in a matter of hours! They gave me a very professional feeling. Moreover, they seem to pay attention to any user feature-request.
In summary, I am very happy with this product.
