Unable to read burn DVD disc

After burning a dvd, data format, and reinserting the disc, I'm unable to read my burn dvd. Aparently, when I click on the dvd-rom icon, my windows explorer hangs. My dvd writer is 16X Sony DRU 710A. I tried it out on 3 different bands of dvd, TDK 8X , Sony 16X and Philips 8X. It all didn't work. I'm pretty pissed by the ridiculous idea of not being able to open the burn disc. I even tried burning it on 2 different softwares, nero and dvd decryter. SERIOUSLY need help!!

This the error i got from burning through dvd decrypter.

Forgot to add: I have updated it to the latest firmware. I'm running of windows XP SP2. It was working like this for quite a long time, bloody pissed.

Are you sure multi-session is turned off in the burner software ? ?

If it isn't the burn is not finalised and the DVD will show blank.

DLoad and install ISOBuster and report what it shows on those DVD's....

Did that drive EVER work correctly? If yes, than what has changed? If no, then get it replaced.

Please advise if all of this software is a complete legit copy on a shiny CD with the manufacturer's name on it or "versions".
