Video-Tutorials vs. In-Person-Classes. Does it matter ?
No. It doesn’t.
You can learn just as much from a video as you can from being there. The difference ? The kinesthetic information is missing. Truthfully ? You’re going to miss that anyway because the class is blind-leading-following-the-blind.

Discomfort
Far too often we experience ‘discomfort’ when dancing. Most of the time we discard it and just accept it as the price we have to pay in order to dance with X, or so that we don’t have to sit through yet another milonga tanda, etc. Sometimes we feel that discomfort, and sometimes we don’t but in general it’s there, most of the time.
