Are there any genuine "work from home" jobs out there?

I have checked out lots of different sites, but I can't get a straight answer to "what is involved, what do I have to do"????  I have watched videos of people showing their bank accounts and how they make thousands of dollars per day. I have even spoken to a nice young man over the phone who assured me there was no selling involved, no cold calling, I don't need to be a techno computer whiz etc etc, but he still wouldn't tell me what I would actually be doing.  He just kept repeating "watch the video on our web site, pay your money and get our training cd's". 

I regularly get emails telling me to check out certain sites, limited opportunities are available etc., but when I google these sites, some are obviously scams, but most of them make no sense to me at all. One was for a budding pop star telling me to watch him on you-tube!!

So, I can only conclude that the only way to make money from home is to have your own web site that sells How to Make Money at Home cd's!!!!

If there is any person out there who started working from home through one of these websites, I would like to know how is it going and  WHAT DO YOU ACTUALLY DO?
