I own Osterlind's 13 steps on DVD from L&L. Classic stuff. However this updated recording from
2015-ish vs the 2002 L&L is refreshing and up to date. The original 6 DVD set are single layer
discs, this newer 4 DVD set is Dual Layer, each disc uses just about 8 Gigs per disc. The Bit Rate
averages about 6mbps, which destroys the downloads as they are about 1mbps. If you are truly serious
about the 13 Steps, get the 4DVD set! Worth every penny. If you watch a DL on a 40inch 1080p TV they
look terrible, whereas the DVDs look very good. Master the 13 steps and you can easily make your
money back with one Gig :}
