i have problem making a backup copy of "lion king, Nemo, and Cat in the Hat." The problem is that it would read the dvd fine, but when i put a blank recordable disc it would read err when i click "write". Then it waits again for another blank disc to be inserted. I used dvd-r, dvd+r, and dvd +RW. The brands I used are memorex and tdk media. Can someone tell me what kind of disc media i need to use or any suggestions or have experience w/ my problems?
