I really need to find a store (B&M or Online that sells the following. Fuji DVD+R 50 Pack (Spindle) 4x Speed. UPC # 7410175059 I've tried Fuji 8x speed DVD+R, but they don't work on my machine. A friend gave me one of the 4x speed and they worked perfectly. He forgot where he bought them from, but still had the wrapper, so I tried to do an online search and couldn't find any store that carries them. Any help is appreciated.
