I've the same identical problem...
I've used the official PowerDVD XP patch from Cyberlink web site.
The new function Virtual Speaker is unavailable (gray), and the button to Buy Sound Pack (I've already all!!!!) is now active.
I ahve both the standard and deluxe versions so I tried the patch with both... and I agree their must be some bug as after installing either of the patches, on the deluxe version, the audio options are not available.
Strange that the patch that we leaked before the official version had the extra WMP9 decoding image on the background and had a company date of - 2003 !! very strange indeed!
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
