Greetings to all, I have the opportunity to purchase Cyberlink's Power DVD Ultra at a very good price. I have no interest at this time in this software's high definition video capabilities. I am only interested in its audio enhancement features (virtual surround sound, sound expansion, etc.). Does anyone have experience with this software and could tell me something about it? I am now using the 30 day trial version of Nivdia PureVideo which is really giving me sharp pictures in Windows Media Player 11 and the sound of my Sound Blaster 5.1 surround sound speakers is unbelievably better in comparison to the sound I was getting without this software. I do not want to install Cyberlink and maintain Nivdia PureVideo because of very possible software conflicts. Thank you.
