Here's some more then. I assume that you have a so-called 'Universal Remote' that you wish to control the Liteon DVD recorder. That is to say a remote that you bought in a shop not the one that came with the Liteon box.
The code for the DVD box is the responsibilty of the universal remote manufacturer NOT Liteon. You did not say the make of the universal remote so I assumed you had an all-in-one and pointed you to their web site.
