For watching DVDs my computer has a Sound Blaster Live Platinum 5.1 with a LiveDrive IR, and a Hollywood Plus DVD Decoder card for occasionally outputing to TV. I would like a good but relatively inexpensive speaker solution to compliment this setup. I had originally planned on buying Videologic's Digitheatre DTS. However, considering that Klipsch is about to release a 5.1 setup, and of course the rave reviews of their 4.1 speakers, I am thinking about changing my mind. Unfortunately since I have already purchased a few DTS DVDs, and there isn't a DTS decoder available from Klipsch, I am curious on how I should proceed. Should I get the Klipsch 5.1s, not use the Hollywood Plus, and go for software decoding via WinDVD DTS? Should I just forget DTS entirely and use the 5.1 solution I already have? Or...since I have a Playstion 2, should I just take my computer out of the equation and use it with the Klipsch 5.1s and a stand-alone DTS/5.1 decoder? If so, what company should I get the decoder from? Would it be easier if I just stick with my original plan and get the presumably inferior Videologic Digitheatre DTS? I don't want to spend more than $700. Any suggestions would be greatly appreciated.
