My (very basic) DVD player is connected to my (also very basic) TV with RCA cables. My laptop plugs into my TV with an S Video cable (so I can watch Netflix streaming, etc). The problem: if the S Video cable is plugged in (even if the laptop isn't connected on the other end) the TV won't recognize the signal coming from the DVD player. My solution is to simply unplug the S Video cable when I want to use my DVD player, but ideally I'd like to keep it plugged in and have some sort of switching mechanism. Is there such a product and if so, can someone provide a link? Thanks!

Hello. I have lost my remote for my Sylvania SRT 2319 and am trying to program my Time Warner Universal remote to work with it. I have found the code and the remote will power on and off the TV but it will not control any other features. Any time I press the channel key or a number key the CBL (cable) device button blinks, like it's not registering as a TV button. Does that make sense? What can I do?
