How do you pronounce this word?

[Rev. Rye]

I pronounce it dis-shev-uled, personally. Then again, as someone who managed to learn to speak largely by watching television, from programs from areas whose approaches to the English language varied wildly (with a remarkable mix between American shows, British shows, and British shows dubbed for American audiences for some reason), and sometimes, I'd end up with pronunciations that nobody uses, I might not be the default source for pronunciations.
