I have a memorex DVDrw working for a year now. Today it gets an immediate error READING the file to burn. It burns a CD ok. It reads a DVD ok. I tried Fireburner and Roxio, both get an error. The DVD is a 2ndry master with a CDrw slave. I pulled the CDrw, no help. I moved the DVDrw to the Primary slave, no help. I put the DVDrw into another system, it works fine. Device mngr shows no problem. I can only think to reload Win2k. I can think of no software lately that may have interfered. Anybody seen this b4?
