Pfui, that thing is uhhhg-ly! How do they come up with 'rent'? Just saying 'runt-gun' or omitting the e and saying 'ront-gun' would be better than that. The correct pronunciation would of course be rönt'gun, where the ö is pronounced like the French peu or of course like good ol' Goethe. And yes the consonant t is included too;-) As for how the r is pronounced correctly, well let's just say it's nothing like that recording.
Now I'm starting to realize why English has the somewhat absurd 'x-ray'.
