Hrmm.. this is strange.. looks like there are different versions of the image floating around.. Can you send the link to the torrent you downloaded? Mine was from:

http://frankyflip.dns1.us:6969/stats...829977c7d573d7

filename is bmw20062.iso
its a 4.3 gig ISO of the DVDROM. The title ends up being CD_5171 when you burn it, and my nav rejects it..

anyway, post your torrent link and i'll compare them.. hopefully they're different and we might have something here..
