How much data does an average Hulu user use in a month?

I asked in another forum, but I didn't get a good answer. I have a limit on my home Internet service and the overage charge is VERY harsh.I know there's all kinds of solutions like a DVR stuffed with the stuff you'd actually watch. I hear some buy old DVD collections on eBay, load it onto a DVR and make their own media server.I don't want to waste bandwidth on things I can get at a yard sale for $1.Anyway, if anyone knows...
