I think PCM is old age. Using a bitrate of 448 I don't think anyone realises a difference to AC3. But maybe some of the freaks here do. Anyway, I do like to download stuff, so I care for downloadable sizes. Also I consider dual layers to expensive still, so I think it is nice and very sufficient to pack highest possible quality on a single layer DVD. Besides Suspiria is a Dario Argento movie and those were never famous for their sound quality, were they?

And one more thing... a short while ago I read "2.0 Dolby Surround" Now how is it possible to have surround sound with only 2 channels?
