Couldn't agree more, it's the big failing of the IT industry. Manuals 
detailing features are not what customers want, they require "how to" 
tutorials. I had a look at some Youtube videos but in the end the best 
help I got was from a guy on Stackoverflow.com who gave a concise answer 
to the multiple audio streams issue:

To copy all streams do this ....
To copy all audio streams do this ....
To copy only 2nd audio stream do this ....

For the first time I understood the relevant options listed in the help/man.

In the 90s, I had a part-time venture supporting a guy who wrote a 
client/policy database for financial advisers. He was a brilliant 
programmer but by his own admission hated training and recognised he 
wasn't any good at it. So I would do the training for his customers and 
wrote loads of "how to" guides based on my own practical experience of 
using the database. I was always taught in sales training to "sell 
benefits not features". There's a skill in disseminating technical 
information in a way that the layperson can understand, unfortunately, 
it's not something that all techies have. Fortunately, it's something I 
enjoy doing.
