Take a trip over to Topfield's website and download the 'Altair' application. This is a simple utility to transfer files to and from your 5500. You will probably then need to think about further software on your PC to make the .rec files from the Topfield viewable on your PC or burnable to DVD. I am currently appraising 'DVR Studio' for this.
While you are there you should grab the latest firmware for the 5500 as it's been updated a couple of times recently.
