Answer 1

if you have a av reciever you could plug everything into that and have the outputs(2 cables tops) go into the tv.

Answer 2

Try getting a tuner. They look expensive for the "higher quality brands" but really its all for the name. A good tuner can be bought for $500. PLug everything into that and it should work better.
