Ok, I have gone through quit a bit of the board and want to make sure of something. I am getting a new computer and the ProMedia 5.1's whent hey come out. I want Dolby Digital surround sound. I am going to get a Soundblaster Live! XGamer 5.1 sound card. Would I still need to get WinDVD 3.0 in order to get Dobly Digital? Would I need anything else? On a completely different note, has anyone here used a video out to use your TV to watch DVD's played from your computer? How is the quality? Thanks
