Good but not perfect Rated 4 out of 5 stars

I just would like to able to select resolution automatically for html5 videos 720p because the addon is changing the windows size of the youtube video, not the resolution. Also I would like to be able to start the video stopped until I click to play, better if it start loading but don't play until clicked.

This review is for a previous version of the add-on (1.0.4.1-signed). 

Thanks for your review.
The default video resolution setting on youtube videos is auto, which theoretically should switch to the right resolution automatically. This does unfortunately not work correctly, but I am already working on a workaround.
About your second suggestion: I am not sure if this is the right addon to do this, because videos that do not require this addon will also start automatically, but I will think about it.

Edit: I just uploaded version 2.0.0 which includes a function which checks if the video quality matches the video size and changes the former when necessary.
