I am a complete newbie to this. I have a Sony DVP355 DVD player and would like to convert it into a good home theatre system. I would like to spend on something less than 200$. My initial conideration was Creative 5.1 5700. Then I read about Creative DDTS-100 decoder and Creative 7.1 T7700 combination. Which of this is better within my budget. Am I in a totally wrong direction. Please guide me.
