I recently purchased 5.1 promedia system. Its working great for my computer, but I would like to find some way to connect it to my tv and dvd's audio input. I would like to use it as surround sound for my entertainment center. I've been looking all over the place to find out how to do this, Best buy, wal-mart, etc.....nothing helps. If there are cables out there for me to do this, please let me know. Thank you
