Setting up MythTV and getting disappointed

I was not very impressed by the MythTV installation process (after having installed the packages for 0.21). The documentation does not really explain well what the different steps mean, but instead repeats the same labels as on screen with little or no additional information.

So if you get stuck because of something, the documentation does not help you at all. Lost a good hour because of doing the same things wrong over and over without a good explanation. And then because of sheer irritation simply added all the missing values directly in the MySQL database. Something was not right...
