Hitachi HDT725040VLA360 problems

I got the Hitachi HDT725040VLA360 dvd writer with my new vista computer For some reason, it won’t read a lot of dvd-r and label them as new dvdr even though there are data on it. It also had trouble burning the ridata 16x dvd-r and hp 8x dvd-r, only the smart buy 8x dvd-r works on it. Is there any firmware that I can flash it with to fix this?
