I second this motion! I believe it has to do with how the videos are embedded in each page, there seems to be a format change that’s stopping Youtube play features. Jason, if you read this- it might be your most pressing bug. I, of course, could be biased- I pause and play your sections before moving on to the next phrase of a tune, so the ability to rewind and rewatch is very important for me- even though I know you have the fingering below. If you would like I can compile a list of pages that have playback issues so you can send it to whoever you have to help with troubleshooting. As is, I am skipping over several tutorials because of this issue.
(I feel it is important to say that this site is still my prime spot and it seems to be taking off very well.)
