I used Vlite to install Vista Ultimate on my system, I keep have major problems with itunes. My Nano and Shuffles won't be recognized I have removed and re installed itunes in the order per Apple. The funny thing is I connect devices to XP or 7 and no issues... On this system I get driver error. I am wondering if it's vlite install since I had to mod the reg to get SP2 to install. I am about to purchase 7 but not sure my issue would go away.
