I have a toshiba Internal Dvd Burner sd-r5272. I've been burning with no problems (over 100 Dvd's) until I switched media (could'nt find in stores anymore). I was using this: . I switched to Hp dvd+r 16x 4.7gb. When it go to burn it would say that it didn't recognize the dvd (hp).I then realized that my burner is a 8x. So I went and bought a pack of TDK Dvd+R 8x 4.7gb. With the TDK, it would act like its burning and then prompt with a error. I dont know what to do. Do I keep buying media hoping that one works? Any help will be appreciated.
