Distance Learning vs Free Online Education
Basically, is your question is "Is it worth it to enroll in distance learning when you could do the same attending free online lectures?" I believe you can have some good input from  Looking for sources of online graduate-level education and Does one get academic credit towards a degree for open online courses?. 

The bottom line is: online lectures usually don't provide academic credits. So you can't show an official degree to an employer, so it depends on the kind of job you want to do: if it's enough to show what you can do (say, for instance, you want to be a web-designer, then your portfolio is likely to be more important than your degree), then why not. But otherwise, you might have to stick with the distance learning.
