My DTH connection & DVD player both run on my TV set. Each time I want to see the other I need to disconnect and remove the cords of one from the TV set and connect the other. Is there any switch available I can do so without removing and reconnecting?Though my tv has front/rear AV inputs it shows only one at a time.There is just "AV" not "AV1 & AV2" as in my other TV. Please anyone reply ASAP.
