[Orb] Are Further Adventures Beyond Dark Matter DVD's, in 5.1?

Just wondering, does anyone know if the Further Adventures Beyond Dark Matter DVD's, are in 5.1? Be nice to hear The Orb in 5.1 p.s. Related question, (sorry to spam the list), but I know that there are some audio experts out there. I've been using 2 x MD recorders, 4 mics, on my sunglasses, to record binaural, audio soundscapes, on my travels. Both recorders have recently failed. Any advice would be much appreciated, on some replacement, suitably priced, high quality, portable recording devices? Cheers, william, bbbrooo (at) hotmail (dot) com.
