Toshiba SD-1600 DVD Player
does not include dolby digital decoding
My receiver has 5.1 audio inputs for dolby pro-logic but I couldn't use this DVD player with it because it doesn't include a &quot;decoder&quot; which would provide the 6 audio outputs you need.  I'm upgrading to the sony that includes the decoder. Otherwise it seemed like a good unit.  The dolby digital systems are incredibly confusing and not explained very well on amazon.
