i am using Dell Inspiron 600m. I burned some pictures many times on the CD-R but for the first time when i tried to burn some of the videos on DVD, I keep getting "Cannot find a driver" message.hl-dt-st cdrw/dvd gcc4244 is the name of the drive under device manager. After talking to dell, i got that the conclusion was tfsnifs.sys case of sonic driver. Also Device manager says: Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. Please help. What to do now ?
