I have a Tsst corp cd/dvdrw Ts-h552b burner running windows xp and it will not write dvds anymore. It will read a dvd-r as a cd in the drive and when i try to burn it show the drive as being a CD drive in My computer. I have tried many differnet things including a firmware update, unistall drivers and nothing works. This problem ocurred after doing a system recovery of windows xp. Under the device manager it keeps showing that my drivers are the windows drivers. If i put in a cd or a commercially recorded dvd, the drive will read it and play. But, i need to be able to burn dvds, not just cds. i know it is a software problem but i can't find the solution. any ideas on what to do?
