Hi, I recently bought the Samsung BDD8500 Blue Ray DVD / TV Recorder but when I plugged it into the same aerial socket the TV was using it only seems to pick up half the channels. The TV is also a samsung with an built in HD tuner and this doesn't have problems as such. I've tested it at a freinds house and it worked ok so I presume I need to boost the signal. There is already a booster in my loft which splits the signal to several different aerial sockets but it was already there when I moved house and may not be very good. Is my best option to get a better booster unit to replace the old one or can I connect them in serial to boost it further? Any other thoughts would be appreciated. Thanks.
