I thought you meant if you do it from your pc as opposed to a online sight youtube can see you or something like that LOL.my wild imagination at work.
P.S.
I added more to my last post ,saying that your theory about youtube separating there audio and video is a good one given the facts we know.
Im hoping that its as simple as savefrome.net patching the problem like they do with the changing codecs. However this new problem seems different and unprecedented.
Ultimately I may have to learn advanced methods to get all the desired results. Ant seems promising given the results you guy had. I will try It Asap.
