To say it out loud, the problem is that you are using MAC.
On a Windows system you can connect to ANY vpn and then go to youtube (not Hulu!!) and then launch
Jaksta and then record the youtube stream (=download!) losslessly.
"Jaksta for Mac" is different product from "Jaksta".
And "Mac" is different from "Macintosh".
On Windows, we dont have any problems with vpn and Jaksta.
On Mac, you do have problems with vpn and Jaksta (according to you); BAD NEWS: since you're on a Mac there is no solution to your problem, sorry. (other than wait)
