Hope this isn't a double topic and that i could be useful for other people.
In the specific video im looking fore, Dave explains a "problem" some people had with oscilloscope, where it won't go lower than 10 mVpd (while it should to say 1 mVpd), he than goes on explaining that it's because you need to manually switch oscilloscope from factory set 10x probe, to 1x. Then he goes on explaining how some oscilloscope do these automatically. That's all i remember.
I have tried and tried looking for it, but just cant seem to find it. Its probably that case of where something is in front of your nose, and you just cant see it. Or more likely i don't know how to search for it.
Anyway, hope someone can help.
