As close to as you are going to get.
Use Prassi or Nero,
guides for which can be found on
www.psxcopyworld.co.uk
If using any Windows other than XP and 2000,
you need a patch for Prassi, to split the image into 2GB bits.
This can be found on the prassi web page. Otherwise you will get read errors.
I made a copy of this no problem using Prassi.
For best results use a good brand of DVD-R such as Verbatim, the cheaper DVD-R media tend to stick on movies.
