What if you try this?

Hello new art I have an LCD TV at home that has a connector for connecting a computer (LCD works as a monitor). A DVD RW video recorder and receiver are attached to it. If I connect video to the LCD and audio to the receiver. And all this through the receiver on the video recorder DVD. Then I’ll just put the DVD on to record from the TV screen during the demo? Will it work out or won't it work out? Maybe I didn’t take into account something???
