Everytime I submit my video that I editted in CS3 to any online site i.e youtube or myspace or sonicbids, the video looks nice and clear on my computer but once it leaves my computer to be down loaded to some place it becomes blurred once it is downloaded. What is the problem?
I use the adobe media encoder, pick a preset that fits my destination but the results are always the same. Am I missing a step?
Please help!!!

Thank you,
