I have a new plsma TV with one tuner,a dvd,and a receiver. No cable box. How would I wire this up to get picture in picture?

You just need to have two tuners hooked up, either through a VCR or DVD with a built in tuner, or even a cable box would work.

As long as there are two sources for the signal, your pip should work just fine.

Good Luck!

If TV doesn't have PIP, you can get a box that will have multiple inputs and do PIP.
