You might have a younger family member, or a friendly neighbour, or a good friend who can answer your question about "where is my downloaded video". After all, we don't know either where it is. And worse, we don't have access to your computer to search for it or check it's settings or even see what you do.

Although I do NOT understand the answers, which I have received, regarding my home computer, since I am NO computer geek, I am grateful that others have taken the time to respond to my questions.
I have decided to give up, on understanding computer tech, since I just dont understand all of the "terms", and !*#$&! abbreviations. Since computer technology does NOT operate on standard English, like we humans do, (on purpose, no-doubt), I have decided to give up on this FOREIGN language subject (which might as well be in Russian, Latin, or African) I will stay with just checking my mail, since the process, of downloading video, and other subjects, are NOT designed for the average HUMAN. They are designed totally, and solely, for high-tech, advanced degree, and multi-linguistic, computer nerds.
This is why this "normal" human is giving up on this "tech-monster". I am just fed up with constantly read about things which I do not understand, and which are created NOT to be understood, by a "simple man".
Give me a pen, and paper, anyday. THESE, I understand!
