The old videos were better

I think the old videos linked from youtube were much better. Now, the videos buffer a lot, a 14-minute video can take up to 25-30 minutes since I can't change the quality, and also, taking a YouTube link and putting it on Solvely is much easier for me to have extra practice than dealing with transcripts (since sometimes there are long names that aren't written in the transcript and the teacher doesn't pronounce it). And the eternal problem of pausing by the space button. I still can't figure out how to do it, it just somehow works sometimes and sometimes doesn't.
