The TS files in the tutorial are recorded from some live stream.
As the original TS is not available anymore, they can not be reproduced.

Of course you can record your own TS and use the tutorials with your own
files.

The same is valid for all single sections (*.sec).

Some files in the tutorial like keys.cw, big-file.raw, example.m2v or 
RootRelook210* just contain some dummy data that are used to create 
new TS files. You can either use them or choose your own. They are only
present to provide some data, the contents does not have any meaning.

As there are no sources available, the class-files for the MHP tutorials
have been removed.

Some gimp made pngs also disappeared as the xcf-file is missing.
