Hello. I am new to making the connections, and am trying to plug in a S-Video connector to my cable box and TV. I cannot plug it in. Please give me some advice on how to plug in the S-Video jack. It seems to go partly in, but I don't want to force it and bend the little connectors. I think it is oriented correctly, the small black plactic rectangular plug is on the bottom. Please give me some suggestions. Thank you.
