How do I connect vcr and DVD both have red yellow white plug in going to tv

Solution
Assuming that the TV only has one AV input your best option is to buy an AV input selector.
You could connect the VCR AV out to the TV AV input.
Then connect the DVD to the AV input on the VCR. Select the VCR as your source on the TV and line input as you source on the VCR. You will lose some picture quality on the DVD.
