Change Booktype On Sony Dru-710a To Dvd Rom

I have read some of the posts on how change booktypes, i need to change the booktype on my sony dru-710a so i can back up a navigation DVD-Rom. I have installed Omnipatch, but can not get it to load firmware. I have also tried to use the software Booktype, but after I change it it will not let me write. Please offer any suggestions, I am a newbie so be specific and easy on the the jargon. :bow:

please don`t crosspost, just 1 post in the liteon forum should do.
