Learning complex things is like climbing a stair.
Start in small steps, learn small steps, only move forward when you feel confident enough to do so.
If videos / tutorials are (too long) for you you can do the following:
Start:
– Watch a video for 10-15 minutes first
– inmediately start to birng-into-practice what you just have seen, learned
– Look for extra tutorials (outside the human rigging dvd channel) when needed
– Go forward with the next section of the video
– Goto Start until you can dream this section
Then proceed to the next video… How does that sound for you Techworker1 ?
