It looks like the bobbin thread is't threaded right, it should go in the tension spring and comes out again sort of nine-o'clock, then it goes straight over the bobbin to the hole in the needle plate. There is a small cut at the end of the bobbin cover; when you draw up the thread it makes sure it is in correct position. Make sure the bobbin turns the correct way once it's in. A 201 has the bobbin in the oposite way of a 66 or a 99. Once you get it, it is very easy.

Sorry, I have to take out my 201 to get this right, I keep confusing this going from a 99 to a 201, I need to have the machine in front of me to get it right LOL

When I look at your videos, it seems to me, that you do not hold the thread end with your finger when you start the stitch. You always need to do that. Normally a needle plate and fabric is needed for a proper loop to be formed in order for the hook to catch the needle thread. You may be able to catch the thread anyway, but it is harder for the machine this way.

And yes, as Appin write, you have got a class 15 bobbin in. It should be a class 66 bobbin.
