I Just had this problem as well, although it was with an IDE DVD drive. I was getting hung up at the same place. I would eject the dvd and re-insert and it would come to the country/language screen and then I would start the install and it would say CD/DVD needs a driver. I beleive it is a firmware update that it needs (at least that is what MS support thought it was). They ended up telling me to install it on my second HDD through booting into XP (I wanted to dual boot anyway) and it installed without issue. Hope this helps, if you havent figured out the problem already.
