for some weird reason my dvd drive can't read some blank dvds. i use to use Sony DVD-R Ver.1.2/1X-8X, yesterday i went to the store and bought Sony DVD-R Ver.2.0/1X-8X and my dvd drive wasn't able to read it. TEAC DVD+RW DV-W58E is the model of my drive which came with my Dell computer. I tried installing firmware but it still doesn't work. Does anyone know why this is happenin? thanks for your help!
