I'm glad that you find the video useful. It helps a lot, like what you're doing now. recording your play and analysing them with other more established players. Most of the time when we record, we still won't be able to see the mistakes. We need someone else to point them out. All credits to you for this.
Now, about your set up.

You must realize that TG has quite a hard rubber/sponge than some of other european rubbers. To fully utilize these DHS rubbers, you must have power. Otherwise, the ball will just drop into the net...just like what's happening to you now.
Here's the logic, if you're a hard hitter with power, when you make contact with the ball, the ball will sink into the rubber, the sponge and ended up at the blade. Then all these three elements will propel the ball out with loads of speed and power too. If you don't have the strength, the ball just might only penetrate the rubber, and a bit of your sponge. As a result of this the ball drops into the net, and they will go around saying the rubber has got no power/pace.
That is why we always recommend softer rubbers for beginners.

Over the years, when you have a more developed technique, you may incorporate power in your shots, and at that time you will realize that soft rubber that you've using is too slow.

Only then you may use a harder rubber to take your game to another level.
