I cannot recommend any DVDs but between Bruce Lee's Fighting Method and Tao of JKD I would suggest getting both titles if you can. However, if you cannot or wish not to have both titles and want a recommendation between the two I would go with Tao of JKD.
But there is another book that I would personally recommend above Tao of JKD and that book is Jeet Kune Do: Bruce Lee's Commentaries On The Martial Way by Bruce Lee and John Little.
Best of Luck To You With Your Book Search.
Take Care,
Osu!
