Nope. Just the regular two stereo contacts.
The reciever needs an analog signal to work with some of the surround mode's apparently.
Neo 6 Channel(or DPLII 6 channel) and LPCM from Laserdisc "beats" every DD 5.1 track I've ever played on DVD. IMHO, a really great upgrade to the old and pretty lousy dolby prologic which I never liked.
