I get many things done by using creativity and common sense like

instead of z try all alphabet - a,b,c,..i, index.m3u8, playlist.m3u8, etc.

Here changing alphabet 28 times multiplied by number of m3u8 words I would try
lead me to think this is better done in educated way,
and would like to know educated way of getting this.

Could you give me some guidance what to read?

Using wireshark to see master.m3u8 or plain book worth reading ?

So far, you helped me A LOT.
