We have 2 of each and a Digital box. The Digi box caused more problems than the others put together!

Of both sets, we have a vid, a TV and a DVD all hooked up together. The only deterioration we get on picture is when we turn the DVD on the smaller TV, which runs on an internal aerial - NOT the big external one.

Most DVDs will give you a working diagram of how to wire it up. You may need extra leads - we had to purchase an extra scart lead (23 pin) and an extra aerial lead (7 pin round plug)FOR EACH EXTRA ITEM to do so. These are quite easily found.

As long as you have a circuit loop from the TV through the Vid and the DVD and back to the aerial, you should be able to work it. If you don't hook the aerial via the Vid, you will lose the signal and be unable to record from the TV. That was our problem with the Digibox - getting the right signal from the box through the Vid to give us a picture.

Good luck with it!
