Ok im looking for a bit of help from the more signally minded. The current aerial set up in my house is the main antenna runs into the front room to the sky box then out to the rest of the house using a signal booster (big house). This is a legacy set up from when sky was analogue so we could set the sky as channel 6 in each room and watch what the sky box was set to, basically a simple Sky Multi Room. Now i have just installed a new blu ray player in the front room with a built in FreeView HD, the aerial now runs through this with the sky box removed from the loop. However since doing this it has screwed the signal to the rest of the house with some freeview channels giving errors of "channel not tuned" or very juttery picture to others. Could this be a faulty freeview HD unit, or a problem with the antenna not being good enough, or the old signal booster not liking the HD digital signal?
