Looking for a video expert to give some advice. Just bought a 37" LCD TV and the salesman recommend us to buy some cable that look like RCA TYPE COMPOSITE VIDEO CABLE . Each cost around $88 dollars and I need to buy 9 of it. 3 will connect SCV digital box to LCD TV, 3 from SCV digital box to DVD recorder and another 3 from the DVD player to LCD TV. He said it will enhance the video output and maximise the HD LCD TV. Any expert out there would like to comment ?
