Chess is no TV Show.
That's a bit excessive, there are some very good ones (depending on what you are looking for). The endgame series is nice if you want to improve your endgames, the Aagaard NID/QID repetoire series is good, the Andy Martin Czech Benoni one is good and at least some of King's Powerplay series is nice. Of course you could question whether you get enough value for money given that the contents are of course less than what you would get with a book or one of the "old-fashioned" Chessbase opening CDs. On the other hand the good ones are a bit like a series of lectures by strong players, which is of course beneficial. I find that in the Shirov and Kazim DVDs that I have seen the presentation was quite dry and unengaging (a problem you never have with Andy Martin, but in exchange on some of his works his analysis is just too light, maybe the target audience is much weaker than me, or it's just trying to get something out quickly).
In fact some of the old opening CDs (without multimedia) were very poor lacking explanations, structure, organzation or any sort of guidance (even the content wise very, very good CD by Marin on the Catalan suffered somewhat by the organsiation of the material).
Coming back to books, I just looked at my bookshelf and discovered "Flank Openings" by Ray Keene and "How to Play the Caro-Kann defense" by Ray Keene and Shaun Taulbut, two books that I think are very bad and did not help me, at all. On the other hand next to that (just ot be fair to Keene), there's "The English Defence ...e6, ...b6, ...Bb7" by Keene, Plaskett and Tisdall, which is a really good book with a lot of useful analysis, interesting ideas, which I keep checking when someone has proposed yet another supposed refutation of the English Defence.
