Wooooooooow I can't f..... believe it, I read the djtaz's post saying that he re-made the .iso from a burned one with ImgBurn, so I was about to do the same, when I realise that the physical info of my DVD's says "Disc ID: RITEK-R05-01" and with my working DVD's says "Disc ID: MCC-004-00", both packages are exactly the same Verbatim DVD+R 16X and the DVD itself looks with no diference with a fast look, but now I can see a few tiny diferences; I guess piracy in Mexico it is a big issue....!!
