Hi. I have a LG 4167-B and since the last week it is working perfectly. Last week I had a problem and I needed to reinstall the DVD Drive. Well now it does not work. I think the problem is the Driver used by Windows XP to install the DVD Drive. Windows use a generic CD-ROM driver, so the DVD Driver recognize CD, DVD, but just burn CD-R or CD-RW. I tried to update the firmware (DL-13) but it still does not work. Somebody can hel me? Thank very much.
