Hello, my name is Steven and im new to theater systems and hd tv's. I'm confused and need help. I am so glad I found this forum. As of Now i have a 42in. samsung tv, not sure model, With a Ps3 and wii hooked up. My system is an older 5.1 sony tuner with the sony 5 disc dvd changer. I also have a Rca 1200 watt home theater system with no tuner as of now, The reason for the rca, is that it plays all discs, mp4 ,divix, etc.. I want to up-grade when money is good, (going to college full time with no job sux) forgive me if i sound dumb when i post for a while since I'm Very new.
