I am new at this and I need some help.Here is the setup Pentium 4 3.0 Ghz 512 Mb Ram ATI Radeon 9600 256Mb ram 160 Gigabyte Hard disk Creative Labs Audigy2Zs 7.1 THX Is this is going to be a good setup? Does a good soundcard makes a difference regarding sound quality?The computer is going to be hooked with an amplifier. What kind of software do you use to play the Dvds? I am going to have a better picture and better sound than if I buy a DVD player such a Pioneer 868? Any help is greatly appreciated as I told you I have no experience regarding projectors working with a homecinema pc.
