Help! I have brought my multi-format TV, VCR & DVD players to the USA and while they play both video & DVD formats perfectly, I can't get a proper picture or any sound when I have the TV hooked up to cable. The picture is perfect as I tune any channel in, but when I save and exit the channel, I get this problem. The TV System is set to B/G and cannot be changed, which I think may be the problem. Is there a way to fix this? PS. The cable works perfectly on any other TV
