[Mario[_2_]]

Hello,

I have a Bang OlufsenTV surround audio system Beosystem

Its a Tv with four column speakers which are powered and aplified as
you knwo the bang olufsen beosystems

Now I have changes TV to a flat screed digital TV but I would like to
still be able to use the Bang Olufsen column speakers, how can I
achieve this?

Does any one sell a system that will input audi/video sources and
output them in surrong to the Bang Olufsen Beosystem speakers?

Thanks,
