I have also taken several distance learning (online) classes in the past. Some were great, others, not so great. I had an especially hard time with math because I needed someone there to explain it to me step-by-step. I just didn't get it, and although I finished the class with a C, I don't feel like I learned anything in that class. On the other hand, I took two english classes online and made A's, and it wasn't any more difficult than going to lecture in my opinion. My advice is, if you are good at the subject or if it is not an "important" subject, go for it. Otherwise, stick with lecture. I personally will not take my bio classes online, because I'm afraid that I won't get as much out of it and it will cause me to do poorly in subsequent bio classes.
One more thing - I've never taken video classes, but some of my friends have, and they believe that the assignments/tests in most video classes are substantially more difficult than lecture or online. They found the tests, in a multitude of subjects, to be mostly essay and fill-in-the-blank, with no answer choices given.
I had a hard time with distractions at home, and I don't even have kids. I was home-schooled during high school, so I thought I'd be able to discipline myself to keep up the work. More often than not, though, I found myself rushing to get an assignment started/completed the night before it was due. Good luck in making your decision!!
