I am wondering about playing DVD's with this recorder. I have on older Toshiba DVD player, but it has the DTS Decoder and Dolby Digital. Does this recorder play surround sound when you play DVD's. If so what formats does it support. I read somewhere but can't find it now that it doesn't have a DTS decoder. I am trying to decide if I will be better off watching DVD's with this recorer, my old DVD player, or getting a new DVD player. Thanks for any advice.
