Video speed slow down to 80%
The video speed feature is a useful idea.
You seem to have focused on making it faster for skimming thru' long courses, I suppose, which is great, however, I mainly work with language learners, and the ability to slow the video down slightly is also a great feature for them. At present you only offer the option of slowing down to half speed, which is too much and distorts the speech. After experimenting with various players I concluded the optimum slow down to be 80% (slows down speech enough to give you an advantage without any noticable deterioration in quality or naturalness)
Thanks for all the great work and making this stuff available to all of us.
