Converting from VHS to DVD these days is pretty straight forward..
It all depends on the hardware that you have and what software that you use.
Firstly you need hardware to connect your VHS player to your laptop/pc.
This is what I use, Ion converter, this will allow you to connect your VHS Player to your laptop using the 3 pin connector (Red, White & Yellow) to your laptop via the usb connection.
Secondly you will need software to record with, I use Nero but there are many available and the ion comes with basic recording software.
I suggest that you use something other than this, such as Nero or similar as you will be able to produce better quality DVDs and also save your files in a number of different formats.
One thing I will mention, and share my experience in this, make sure you have enough space on you laptop/pc before you start recording as it will take up space. The higher the recording quality the more space it will take up. You must have a minimum of 5GB spare to make one DVD.
If you live in UK, the Ion can be purchased online via Amazon or instore at Maplins.
Hope this helps.
