1) yes, this has been reported several times, it's likely the main issue now ; I'm planning to add a helper to boost your first steps.
2) If the strike time is correct then it's ok, but I noticed (and some other users as well) that sometimes the strike time isn't ; I'm also planning to look into that (it doesn't happen often so it's likely a miscalculation in a specific case or an issue with the new anim system)

1) at 1.24, Djoko is actually very close to the ball ; in term of performance, it's equivalent of TE4 ; the main thing missing here is the extension animation that I hope to add
2) At 1.27, you can do the same in TE4 ; up to 4km/h (with 100% Speed & Toniticty) you can instantly convert your left/right speed to the opposite ; it simulates the splitting step in real-life
3) At 2.02, the ball is very close, you can do almost the same in TE4 (check with the CPU), it might be a tad slower though, so the strike will be less accurate than what it should be ; this movement is a good example of the new stop-break technic that I'd like to put it in TE4 at some point
4) 2.32 ditto
I didn't check the other ones.

I guess you may not have the reflexes of Nadal & Djokovic, or/and you don't see the ball as clearly as them. The future 1st-steps-boost helper should be good for you, too.
