Sorry, the log file is the old one, the asus have replaced the lite-on, anyway the same problem I have with the LG, even that one can't write less than 4x, and yes I read already the suggestion for the DL, but nothing that I didn't know allready, cause I am using verbatim DVD+R DL(the "MKM-001-00" and the "MKM-003-00" and DVD-R dl I did even try with the TDK+R, but no way, following in other forum the discussions about how to make such a DVD, it seems that all the people who made it did it with very low speed such as 1x; 2x; 2,4x, maybe on old driver.
Sorry again for the wrong log file, but trust me now I have even asus above mentioned and I tried anyway on the old lite-on I have disassembled (maybe the lite-on didn't have the best firmware). PLEASE I NEED SUGGESTIONS.
