Apparently I need to sign in to protect the community or s/t

So there was no way to play the video.

Also that blinding flash of white when it starts is unnecessary cruelty

Aj, sorry about that. I think it is YouTube blocking you. I didn't think of that edge case yet so I think my app will keep trying to play the video. Thanks for the report.

You fixed the videos!

This is awesome :)

I had to (was able to) slow the videos to 1/2 speed (no tengo muchas parablas dontcha know) but this is much better training than Duolingo
