Yes, this part is interesting:
"Thank goodness for lossless audio encoding. Heath Ledger’s performance as Ennis Del Mar, while brilliant, has always been slightly difficult to comprehend, due to the actor’s use of a particularly grumbly and deeply pitched voice. I’ve seen Brokeback Mountain on a number of occasions, both theatrically and on DVD; Mr. Ledger’s voice has always seemed difficult to discern and frustratingly unintelligible. Remarkably, with this Blu-ray’s use of 5.1 DTS-HD Master Audio for the film’s audio, I was, for the first time, able to discern some of his most harshly grumbled lines. This improvement alone, makes lossless encoding worth the price of admission."
And it's great have a brand new rave review of Brokeback Mountain written in 2009 for people to see!
