I don't know if this would help but here is a
guide that I made some time ago for HP QuickPlay 2.3, which also lists how you should set up your notebook format and audio issues. To my knowledge, newer dv2000, dv6000 and dv9000 uses a newer codec compared to the old ones. Again, I will see what I can find out about this as I have been meaning to update my guide to include Windows Vista. Unfortunately, I do not have Vista just yet but I will see what I can do. Also, the dv1000 does not support QuickPlay 2.0 but if I'm not mistaken AmigaDude was trying to get it to work. Again, I'm unsure of that.
