sorry i shoudl have explained
if your TV is a MK3 it will have 4 hdmi sockets on so you can just plug your blueray player into one of those and set it on the connections menu, you dont need to use DVI if you use HDMI???
on the BV7 mark 3 the DVI is an output for projector and is DVI D which is not compatible with DVI-I or DVI-A
The DVI connection on a MK2 is an input.
