I have SKY+ with a Toslink lead for Digital sound output to my TV.

Does SKY HD have optical out or HDMI for sound? Are other channels broadcast in Dolby Digital or just the HD channels?

The Sky HD box has HDMI & Optical Sound out (Toslink) - also Left-Right audio connectors.

The only channels that I know that broadcast DolbyDigital are SkyMovies (premier 1 & 1+), SkySports, SkyBoxOffice & the HD channels, could be more but I doubt it.

Heres a picture from wikipedia... (notice also it has USB, Ethernet & eSATA - interesting )

On a Sky HD box you need to connect the optical output up to your system using an optical to sp/diff converter, the Sky HD box does not transmit DD sound over the HDMI cable (as it should). You can then receive DD sound on channels that transmit it which is just the Sky HD channels.

Agreed, just a few more channels with the DD track. If fact Ive noticed my last post was slightly inaccurate, joc in his post is correct a few of the SD channels also transmit DD as you already know I think.

All the HD channels support DD but not all the programs transmitted are DD as that depends on the source material. You can see what is in DD by looking in the program description in the sky epg they add DD to the description.
