Strangest thing with this RV - Have Winegard Model VS-0604/6412 Amplified Video Distribution Center - Antenna buttons pushed. Found out we have to change antenna direction to pick up the same station on rear TV that we've been watching on the front one. Reasons? Fixes? Also, replaced factory installed DVD player with VHS/DVD combo. Rechecked connections a number of times but have been unable to record on VHS tapes. However, we are able to play VHS tapes but only on the DVD setting. Had been unable to pick up the same higher channels on the front TV that we could get on the back one. Read another tip which suggested changing the TV (screen) setting to cable while keeping the Distribution Center on Antenna. Don't know why, but the upper channels magically appeared. Needless to say, we're electronically challenged. Any help would be appreciated.
