Summary:
(1) Beating are not only allowed by the Koran they are promoted by the Koran.
(2) Without wife beatings the family dynamic breaks down and leads to divorce.
(3) Using harsh words towards a disobedient wife is a must, aka spousal mental abuse is an Islamic duty! Don't leave out breaking her down mentally also!
(4) Refusal of sex is a just reason to beat your wive.
(5) Beat your wive with one of the assortment of rods. They are the "Rods of Obedience." Do you see the size of some of those rods. They are huge. Broken bones all in the name of Islam, so it AOK.
(6) Beating one's wife is a Husband's RIGHT. He can't be prosecuted under the law, unless he kills her!

(7) A wife has no right to beat her husband, even in self-defense. "Islam spared the wife of a need to use violence." However, a wife can get another man to beat her husband, but only after she goes to court and the court awards it. Yep fat chance of that happening.
(8) Comical moment in the broadcast: Beating your wife with a handkerchief is considered "extreme" and even laughable. I would do no damage.
(9) Beating your wife sends a message: "I'm not pleased with your behavior."
(10) The cure to the mental disorders of sadism and masochism? You guessed it - BEATING YOUR WIFE!!! Not only does the Koran allow this it promotes it as a cure! Don't take the Koran's word for it, Islamic psychiatrist say it's the cure and regularly tell the husbands of their patients to start beating their wives!
(11) BIGGEST FABRICATION: The scholar actually claims: "No women died from Islamic wife beatings." OK nutbar!
So given your summary it doesn't seem as though you watched actually the video. Perhaps you simply copied and pasted this from another site?
Anyway:
"Beating" is a poor translation from the Arabic to the English. Any linguist, or theological scholar will tell you that this is often a problem when translating texts from one language to another. When we hear the word "beating" we think of violent domestic abuse. Unfortunately that happens all too often all over the world, but the "beating" in this video as it relates theologically to Islam is a purely symbolic gesture in which the husband is to strike his wife with a scarf (or handkerchief as he says in the video) in a way that does not leave a mark on her to symbolize how poorly the situation is. It is the last ditch effort to ward off divorce and it not for every ay use (It is not for everyday acts of disobedience, or for use in arguments). It is not something that is theologically allowed to be done out of anger either. This style of symbolism was passed down from Muhammad's farewell speech through Ibn Abbas.
To cover a few of your more off specific points:
3.) He doesn't say that speaking harshly is a must, he said that it is better for family unity to resolves things through dialogue, not domestic abuse, and he said that the type of dialogue depends on the personality of the women. His talk is quite misogynistic, but he lumps women into different categories depending on what they might respond to best.
The sticks in the video are not something that he is telling people to hit their wives with, just the opposite he is telling people that isn't acceptable.
4.) Not true. Though this is a general cultural belief that persists in many countries (including non-Islamic ones). The refusal of a woman to share the bed of her husband in Islam signifies marital problems. There are a number of steps to be taken before the symbolic hit with the scarf occurs, and generally such a thing under jurisprudential codes comes after months or even years of continued denial and problems. If a guy comes home from work and his wife doesn't want to have sex because she has a headache he isn't allowed theologically to hit her, let alone beat her.
5.) I'm not sure where this one even came from, the rods he is holding are rods that he says are completely unjust to hit your wife with. He replaces them later with the handkerchief that he waves around while talking about Ibn Abbas. And you mention broken bones, but the strike isn't even allowed to leave a bruise let alone break bones.
6.) Once again this happens all too often in developing countries, but theologically under traditional Islamic jurisprudential sets that isn't true at all. In fact even in this video he says that a woman has the right to take her husband to court for issues of mistreatment including domestic abuse. I have actual primary document records of such legal cases throughout the course of the Ottoman Empire if you'd like me to reference them.
7.) This is true. The symbolic striking is something that is generally for men to utilize though there have been cases where women utilize it as well. Islam was constructed during a time in which traditional patriarchal structures prevailed and that trickled into the theological aspects of Islam. We see the same sorts of patriarchal family structures in other religions as well. I don't particularly care for them, but then again that's one reason why I'm not religious.
8.) I think you misread the translation there.
10.) Yeah that was an odd segment, he said "beat your wife in a very specific way". He didn't elaborate on that, and the treatment of such disorders is not an area of Islamic jurisprudence that I have a lot of experience in, but I imagine it shouldn't be among the "harsh beatings" that he differentiates with earlier. Aka leave no mark, and not allowed to strike the face. I could be wrong there though, I've never studied such a case.
