If you want to dive into
Parsifal - an adventure that'll be right for some and wrong for others - DO NOT begin by watching this or any other video. Two reasons:
1.) Most stage directors today are obsessed with presenting their own commentaries on Wagner rather than presenting his stories as he instructed, and the results are always in some way contrary to the spirit and meaning of the work.
2.) Wagner's music is so evocative that the images it will summon for an imaginative listener surpass any possible staging.
After you've experienced the music sufficiently, you can look at various productions and judge for yourself how well they represent the opera.
As for recordings, the ones which I find best capture the mystery and profundity of the work are the live Bayreuth performances under Knappertsbusch, recorded between 1951 and 1964. Just march right out and buy the only one recorded in stereo, the 1962 performance on Philips, for the full
Parsifal experience.

I can't recommend the Boulez or the inexpensive Kegel; both have casting weaknesses and both indulge in some overly fast tempos. If you're in a hurry,
Parsifal is not for you.
