stalker96 - thanks for your explanation. It was most helpful to read a clear explanation that
Jaksta works for MFC in recording mode (ie records while watching stream) and not in downloading mode (ie download stream and leave the page).
Obviously downloading mode in Jaksta is preferrable, but until an alternative is found, I'm happy with the results of recording mode (ie getting the MFC model stream rather than rickroll).
itsme - thanks for your contributions also. I suspect you are the guru here. Hope to hear more of your insights.
I look forward to further constructive comments on the issues raised in this thread.
