downloading to you tube

Downloading to You Tube I lose Quality in the video Whats up?
Videoes are in jpeg format when downloaded to the computor, Is there a better way to do this without losing Quality

I'm not sure I understand the question... but I'll try to answer it.

YouTube encodes video in a lower quality on upload so it saves bandwidth. They spend many $$ every month (some estimates place it in the $1 million range), so if they can decrease the amount of bandwidth eash video takes, they will. I'm not sure what you mean by JPEG or downloading it to the computer, but I hope this answers some of your questions.
