I need "dummies" instructions for someone who does not have much computer knowledge. I managed to download one video, but not another one. I have looked on line for instructions, and cannot find any, so I don't know if I am using the addon correctly. I do not understand the things in the "conversion tool" area. What I want to do is download videos to my computer to then convert and burn them to a dvd to play on my tv. Maybe I need a different addon, but how do I choose from all the ones that are offered?
