Please accept this comment as meaning to be helpful, as I really enjoy taking the video courses on this site:

There appears to be a serious audio issue. In the first episode I needed to strain to understand the speaker as the audio was a little garbled. Was the speaker too close to the microphone perhaps? The presentation was also a little too monotone - not enough inflection. After listening to the first episode, I skimmed the next 4. The second episode was markedly better with regards to the audio quality, but the following three continued to have issues.

As a check on my computer, I re-listened to a different video course I had previously taken on this site and the audio was great.

I would suggest that you may consider recording the tutorial again.
