Is the full length video on this site worth watching? I can't seem to manage to get it going.

I recommend downloading the video. Much easier.
I also recommend people to make the effort to watch it, definitely worthwhile I'd say.

Yes download it and view it at your leisure I'd say. I seem to remember it was quite long!

Yes worth a look for sure. Anyway I've bitten the bullet and will be starting soon. I've got a short holiday coming up, so I'll be starting after that, at the end of this month. Feeling good about it!
