RECORDED VIDEO, FAST SPEED AUDIO?

I recently got rid of the DVR I was renting from my cable company and attempted to record my shows the old fashion way, coxail cable "In" to VCR "Out" to TV. I get the picture but the audio of the recording sounds like it is being fast forwarded as it plays. I have a new flat screen Vizio that i am using. Is there additional input output wiring that needs to be added and if so, where. thanks
