It appears the pawls have gone on the freehub.
You might be lucky and free them off with some release oil (WD40), but unlikely, then you would have to regrease.
You will have to remove the freehub as you don't want to get release oil in the hub bearings.
Probably though the freehub will need replacing.
As per the tutorial:-

as George mentions.

From the look of the bike, it is probably a cassette hub. That means you can try flushing the freehub with some lub as cyclerUK suggests. Otherwise, you may need to replace the freehub, hub, or whole wheel depending on various costs.
@GeorgeET - I'm just slightly confused why you would recommend locktighting a freewheel on. Seems to me that would just make a freewheel that is very hard to remove, but wouldn't work any differently. But maybe I'm missing what you mean.
Well if it was a freewheel and somehow it span off than Blue loctite would help secure it. ( I mentioned that most likely its a cassette)I am aware that rotation would tighten it, however have seen some get loose.The blue loctite is easily removable. Red locktite is mostly for studs and requires heat to remove.
I use the blue locktite as a extra safety item in a few vibration prone or difficult to get at spots. Mostly on motorcycles. Not so much on a bicycle. However if I find a bolt prone to looseness or small fasteners I certainly would locktite it.

Hmmmm.. Looks like you are using the correct tool , does it fit the notched ring slots tightly? Or are you just spinning the gears? Make sure its engaged properly.
Is so you got a stripped hub and need a new wheel. Unusual.
Nice video BTW
Never Give Up!!!
I still think it's the pawls that have gone.
Put a chain whip on the sprockets to stop them turning backwards.
Then turn the cassette/freewheel tool counter-clockwise to see if it will undo?
Can you post a closeup photo of the center of the freewheel please?

Good point cycler UK. However I am not sure about that as I understand it. The pawls lock the wheel in the forward direction and free spin backwards. The lock nut engages the inner sleeve of the freewheel so not sure how the pawls affect this.
Take a careful look where its spinning, Is it spinning on the hub or internally. VJAB.
Ye you can try what Cycler says. I used a chain visegrip to hold the sprockets.You can try wrapping an old belt on it if you do not have a chain whip. Or ask your LBD.

First are you using the correct freewheel/freehub tool? From the looks of your Cassette/Freewheel (not sure so I name both) it should take this tool.....
http://www.parktool.com/products/detail.asp?cat=4&item=FR-5G which has a guide pin in it. Here is a page that has instructions, you will have to scroll down the page a little to see the part covering the FR-5G . You'll also notice in the picture there yours is VERY similar. Here is the link with the instructions
http://www.parktool.com/repair/readhowto.asp?id=48 . I know you must be VERY VERY frustrated, but hang in there as there is an answer for everything

Good maintenance to your Bike, can make it like the wheels are, true and smooth!
You have the tools so you are not a newbie at this. Interesting chain whip combo tool.Too bad it broke.
Looking at the wheel its badly corroded and clumped up big time. Suggest soaking overnight with penetrating oil like Liquid wrench or a 50/50 mixture of acetone and automatic transmission fluid which works great and trying again. Heat would be the next thing , but make sure oil is washed off so no risk of fire.

Just to clear up any confusion, this is an 8 speed hyperglide CASSTTE. It is not a freewheel. The ratchet mechanism is in the "freehub" which is bolted to the hub. The lockring threads into the inside of the freehub. Freehubs are usually replaceable, so if lubing it up doesn't work, you may be able to swap it. Unfortunately, I don't have any great advice in how to remove the cassette beyond what you are already doing.

Dave I agree with you on the correct name. Should have said that. What I am saying if that the lockring on that thing is a real bugger to take off. Park site says it, Sheldon said it, and just about everyone else too. Note on it 40nm. Quite a bit of torque and who knows how much more it is going to take to POP it to the unlock position. The vise idea is <b>not</b> an option. Reason is it just turns and turns. Best way is to get another chain whip tool (think he said he broke the current one), use the skewer to bring the removal tool he has closer to the notches (splines) for maximum leverage or buy the FR-5G, and get something to go over whatever he is using to turn the removal tool for longer reach thus more leverage like what I call a cheater tube bar (seat post would work great). The only other option is to take it to a Local Bike Shop.
Good maintenance to your Bike, can make it like the wheels are, true and smooth!
Also wanted to add try changing having someone else hold the chainwhip in place while you operate the other. Use your body weight if you have to.

Thanks for the video and cassette photo.
Tips for removing the cassette.
Don't press down on the wheel as in the video. (Likely to damage the wheel or spokes.)
Lie the wheel down on a bench or secure in a vice.
Put the whip and the cassette spanner closer together in a "^" and squeeze the two together.
This will give more force.
You could extend the allen key by putting a tube over it.
It will only be brute force that will undo the cassette lockring.
Try not to damage the cassette though.
If you are still struggling then try your LBS ????

Well, if the freehub can spin clockwise, it's pretty much "broken" by definition. You don't have to look inside it to see that.
You can try flushing it with lube to see if it will free up the pawls and fix it. Shops generally push replacing parts over tinkering around because labor is expensive and they don't want to guarantee a 'fix' on an old part that may go out again shortly. I've come across bad and dishonest mechanics in my day. But it sounds like the guy you are talking to is at least fairly straightforward.
