I use the firefox plug-in "Video Download Helper" (dwhelper) and it always
works. Play the videos with VLC.
No need for anything else.
I have one machine I managed to get the free-flash working to play Utube,
unfortunately I did not make good note of what I did, and I have not been
able (maybe not trying much as I prefer above method really) to reproduce
