I am a great fan of learning by doing rather than by acquiring information on an intellectual level and then trying to put it to use in the real world as I have experienced a lot of frustration from that approach.
Right now I don't have time for making tutorials in other mediums. I see a greater priority in making tutorials that show how to import different parts from other files, paint, create skeletons, rigging, animating and show how to create video clips so that there is no missing information in how to create movies.
If the YouTube slider is getting in the way you could download the tutorial with a free program like: Freemake Video Downloader: http://www.freemake.com/free_video_downloader/ and playing the video back with Media Player Classic: http://mpc-hc.org/ which is a nice simple free light weight player.
If you want to keep replaying the video from a marked position, you might find Avidemux usefull: http://avidemux.sourceforge.net/
Although Avidemux is a video editor, it is light weight enough to use just for playing videos.
The way I see it, there is little point trying to learn too much information in a day as the brain can only take in so much at a time.
Seamless should be easy for a beginner to start if you approach it the right way. You will understand enough be able to develop your modelling skills to the point of being able to model a human head, if you can drag control points, insert control lines and extrude points which are all covered in this 30 second tutorial: http://www.youtube.com/watch?v=uCXacwYR5jQ
After getting a feel for modelling by actually doing it, the Modelling a Human Head Step by Step tutorial should be easy to take in if you only try to learn one new feature each day.
If you are stuck on something, please let me know which tutorial and at what time in the video your having trouble following it.
PS if I view the video in youtube in the bigger size (2nd last button below the video sets it) , the progress bar does not hide any of the video.
