Hi I have a Sony Vaio VGXTP25E desktop and I upgraded to Win 7 64bit , I did a fresh install everything seemed to go well. I was able to get the Nvidia drivers for my GeForce 8400M GT and I was able installed Windvd BD 8. I have 2 problems I cant get the AACS upgrade to dowload. The other problem which is much bigger is no Dolby Digtial/DTS via HDMI , I am sure I am using the generic HD Audio drivers from Intel which wont pass DD or DTS. HELP I am sure there are members out there who upgraded this PC. I use it from my media center with 2 Digital Cable card tuners. HELP PLEASE HELP!!!!
