    If you guys could do this for all upcoming videos, that would be great. The split-screen view is horrendous because the slide can get out of sync with the video.

    I've honestly been avoiding regular expressions for years... watching this presentation helped me take my 1st step to learning them.
    I'm only two days into my learning experience with them and I actually find them kind of fun now, thank you Damien!. :)

    Hi Ionuț

    We can't do this for all videos I'm afraid for a number of reasons. However what you describe should be very rare. I wonder if you are hitting a bug in the player - maybe related to bandwidth or similar. I've highlighted this to Dio, our product manager, and he will follow up with you via email.

    Also the speaker was kinda too... Americanish. :-) Even shouting sort of. Topic was good insight into something many of us use a lot. For the final problem I'd probably went with something like '[^']*' instead of greedy/reluctant dot matching all. But he made the right point in the difference between them - and that was probably the intention.
