Operas on Netflix

Richard Wagner, Siegfried, conducted by Pierre Boulez at the Bayreuth Festival (1980)

If you are like me and you a) like opera and b) subscribe to Netflix, you will be happy to learn, as I did recently, that you can put opera DVDs into your Netflix queue. Unfortunately, for an obsessive person like me, this has led inevitably to my spending lots of hours watching opera DVDs and, to make things worse, making suggestions to Netflix about more opera DVDs they need to acquire, so that I can spend more time watching opera DVDs. Is there a program out there for me?
