Google Chrome Plugins and Themes

I'm heartily sick of watching some stop-start "streaming" video & being unable to save it for later viewing or study.
I guess the video makers have their reasons even if I can't fathom them.
I'd hoped Chrome by now would have been a simple answer but the more time I spend searching & reading the more confused I get.

Surely this is such a basic everyday need by everyone that a simple straightforward solution must exist.
I don't much care if it's a plug in, an add on, or whatever, I would just like to be able to do it without messing around with scripts, which from what I can see work one moment & then not another.
Blackcoil whatever it is is, still listed, but the link page will not load.
Would someone please update me & if there is a solution (it needs to apply more broadly than just UTube) spell out in simple terms how to arrange this so that you can save easily as & when required.
Thanks in advance.
Pete

Welcome to ChromePlugins

have you consider using 3rd party applications ?

What version of Chrome are you running?

Yes.
I have spent now more time searching & downloaded a couple for testing.
I also found one bookmark related recommendation.
All after posting, despite spending a couple of hours before requesting help.
In the past, using IE7, I have not been entirely happy with the typical 3rd party offering but lets see.
If you have one that's free, & which you can recommend please advise the link.
Thanks
