You've missed the point totally.
If you want to help someone then that’s great, if you take the time out to find some help then that’s even better but, in this case, if you can't even be arsed to watch the video because it could be a waste of time, then how is that helping.
You got lucky because the video was relevant, but you had no idea that was the case when you posted it.
All I'm saying is that it's a good idea to be sure about what you're posting, even more so when helping out someone who doesn't know know much because it could totally throw them off.
