Robert's thorough on his videos, but he does talk slow and can take a while to cover something.
If you are willing to poke around in your own on Altium, consult the user guide PDFs when necessary, and Google around some, you can baiscally bypass his videos.
The reason to watch his videos is that you can watch 1 hour of blabbing, but you catch a small 20 second tip that in the future will save you several hours of routing time. Such as part placement order, what parts do you route first, placing fiducials before you route, etc.
