Hi tony,
A recovery disc allows you to repair your current installation, it doesn't install Vista.
Have a look at this tutorial:

I don't know if Home Premium allows to achieve a complete backup?
You can use also programs like Acronis true image for example.
If you want to write a DVD which includes Vista+SP1, we are talking about this tutorial:
