I've had the dvd for awhile and I highly recommend it. I even wrote to the guy who gives the instruction to request another (he said he forwards these to the powers that be, so anyone doing the same would be helpful).
As for how it compares...it's similar and different. Similar in that he shows you the licks at speed and then slows them down to a manageable speed. Different in that he shows ALL the licks for the song, both Jerry's and Bobby's. It's fun to learn the Jerry lick and then while he is doing the Bobby lick, play the Jerry lick you learned. He also talks about what effects to use and uses different guitars for the different sounds (Jerry/Bobby). He also doesn't include any tab, which is a downside. As far as content, I would say that his is more of the whole song while this site is more comprehensive.
I am thankful for both his dvd and the fact that you folks are starting to put vid on this site. Keep it up!
