Digital TV and Bose sound system

RainyDay,

The scart goes to the AV2 socket on the TV,with the 3 jack plugs going to the Bose Unit.
The TV has AV1 & AV2 scart sockets and the Bose unit has Video input and output sockets together with 4 pairs of audio sockets.
I select dvd/cd on the Bose to play music or films; Video1 to watch analogue channels on the TV with sound through the Bose; Auxiliary to watch digital channels with sound via the Bose and haven't found any else to play via the Video2 slot on the Bose.
Brilliant kit but not cheap; we went to their outlet at Bicester village in Oxfordshire and bought the kit there at a £300+ discount as it was a rebox from a trial. (Bose give a free 30 day trial on all their kit.) Still cost nearly £900 but worth it.
