This video is same old, same old for KJVO people.
Each argument is "The KJV says X, the new versions say Y; X is stronger doctrinally or X fits my beliefs better therefore the KJV is clearly superior."
Whereas a real argument would be "The KJV says X, the new versions say Y; the originals mostly agree with X/Y therefore the KJV/New Version is superior."
Like Psalm 12:6,7 - In the KJV it isn't clear whether the "them" in verse 7 references the words of the Lord in verse 6 or the poor in verse 5. Modern versions make it clear that "them" refers to the poor. This preacher simply disagrees with that translation but makes no attempt to support his interpretation whatsoever.
