I have a Sanyo tv that I have hooked up to a dvd player to. It also runs thru Sattelite Dish or box.. The player and vcr and tv are all hooked up properly but half way thru a movie on the DVD player the movie freezes up. I thought it was my DVD player and so I purchased a new one. The same thing happens. Can it be the sattelite or am I doing something wrong.? Please help.
