I hav a y rca cable splitter (one female 2 male) and i a tying to use it with my xbox and dazzle to record games. Whenever I plug both ends off th cables coing from the splitter into an input i get scrolling black bars on each. Note: I only get these when its hooked up to the dazzle and th TV, if i hook itup to just one it's fine. Whats the problem and or how can I fix it?
