I have a Sony HQ100 TV with a Pioneer Freeview box connected to AV1 and a DVD player connected to AV2.If the freeview box is left on and we watch a DVD the freeview box will sometimes switch the AV's to be the current picture. This seems to happen whenever adverts appear on the channel!! I have found if we watch a DVD with the freeview box left on and change channels on the freeview box this also causes the same thing to happen! Is this a fault or is the TV "seeing" the change in aspect ratio's on the freeview box and interpreting this is a request to the TV to switch to this AV input??(as this only seems to happen with channels with adverts when the aspect ratio changes for adverts and when flicking between different channels with different aspect ratio's) Please tell me this isn't a fault as after THREE FS76U's i will have a break down if this thing breaks!! I love this TV!!
