So this works great, but the one thing that takes away 1 star from a perfect score is the fact that the description seems to indicate many more customization features that don't seem to be present in the module configuration.
For example: 'Manual slideshow enables visitors to select the video they want to watch as well as gives the option to have them automatically in rotation to play.' - You only get the option to show one video during setup.
Eaxmple #2: 'With the slider bar you can early see what consumers are watching and what they think about it through the comments sections, of which are easily accessible through the widget.' errr - no: comments are not visible in the widget...
The other thing that knocks this down another star(and will probably cause me to look for an alternative soon)is that fact that there is no option to remove the developer's link (something I would gladly pay for, but no option is given).
Final straw that makes this a 2-star review is the fact that there is no way to contact the developer to address these issues: their website forums and 'contact us' form are both hampered by a Captcha system that fails to load and makes submissions impossible.
I was able to submit a question using their 'contact us' slider widget on their site but, so far, no response (question submitted 2 days ago).
One thing to be aware of if you decide to install this extension: when you set this up do not input the full URL of the video you want to display as it won't work. Only put it the identifier AFTER the =
So to display 'youtube/watch?v=qogTWKW7CNc' you should enter 'qogTWKW7CNc' in the box asking you for the URL: this is explained in the documentation, but I managed to miss it the first time around
