It's probably the most detailed Sonar video ever. Over nine hours of in depth look at all of the functions, tools, and options within Sonar, insanely detailed was one description I've seen - which was a compliment I think/hope.
It starts from the basics of setting up audio and MIDI interfaces, the options to tweak for performance and stability and then carries on through a full explanation from the basics through to covering the more powerful tools that Sonar has.
If you check out the
detailed content PDF (even that's 11pages - I don't do skimp

) you'll see exactly what is covered and there's a video from the tutorial
HERE which gives you an idea of the style and format.
As an added bonus if there's anything you're unsure about and have specific questions on any of it I'm always here
getting on people's nerves on the forums to answer them.
