I wasn't offering my services, just pointing out that by doing it myself I would potentially be taking work away from someone that does it for a living. As for changing light bulbs, I don't know of anyone that would call an electrician to perform that task unless it was an extreme situation. I do all of my own electrical, plumbing, and carpentry work as well as my own auto maintenance and repairs. I wouldn't charge for my services, mainly because I barely have the time to do it for myself let alone anyone else. I do, on occasion, perform such tasks for family and friends if they're in a bind. I've talked my mother-in-law out of calling a plumber on several occasions and fixed the problem myself (and no, I'm not a licensed contractor of any kind). The point is, those that can, do. Those that can't call a plumber. The risk would be minimal beyond that point since most hackers would most likely not be wasting their time on older operating systems and would be concentrating on what's current. The number of people using XP beyond it's supported life will be far less than users or more recent versions of Windows. Hackers and virus developers go after whatever OS has the most users for maximum effect. That's the only reason Mac users aren't affected by viruses. There just aren't enough of them to make it worthwhile going after. The lack of free program guide data can definitely be an issue, but there are third party providers that will give you the data for a modest subscription fee. It would involve some tweaking in Media Center or whatever front end you're using, but it can be done.
