Can I cross flash my 740UF to BenQ 1640?

Guys, I’m new to this DVD burning thing but I saw a post about a user that cross flashed their 740UF to BenQ 1640 and said that it ended withi his drive writing better etc… My drive makes so many coasters (different table to media from manufacturers)… I was almost to the point of going out and buying me a pioneer and sticking it in an external case. However, I would like to explore the possibilities of my improving this drive… Can any one here educate me on this process.
