Hi not sure where this should go, so moderators please move if need be into the right category.

I bought a new 37 inch lcd tv, and I want to get a surround system, entertainment center going.

I am a little confused about the vast number of surround sound systems.

I currently use a HDMI connection with an up convert 1080p dvdplayer.

I am looking for a good entry level surround system.

Or

I can build or use an old pc with a DVI to HDMI connector and use my computers sound system.

Which would be better, and give me a better experience.

Thanks in advance.
