The 10th dimension video doesn't seem that stretched. He makes a good point of explaining them all, though it took some time for it to melt into my brain.
If you are interested in that kind of thing and want a relatively pain free insight into the science then I recommend the books of Michio Kaku Hyperspace and Parallel Worlds especially). Theoretical physics with the slant heavily on accessibility and explaining the context and the significance rather than just the results.

Michio Kaku is just cool in general. He can talk science and be very accessible about it, like Sagan (a very hard thing to do, if you ask me!).
