I just got a NEC 2500a (Mad Dog 8x). I pulled my old TDK cdr burner (master) out and replaced it with the NEC. Windows XP recognized both drives. I inserted a regular cdrom in it and it read ok. I then inserted a commerical DVD and tried to view it with MS Media Player 9 (just installed through Windows Update). The player would not recognize that there was a DVD in the drive. I also tried PowerDVD3 witrh no luck. Nero 6 recognized the DVD, but wouldn't copy it due to copy protection. I then tried to read a regular cdrom disk in the NEC. It now wouldn't recognize it! I then installed DVD X Copy Platinum. It recognized the drive, but would not detect that a DVD has been inserted. This is also true with DVD-Clone II. However, when I ran the free DVD-Decrypter software, it immediately recognized the movie and made the image files. I used CloneDVD to burn a copy which played in my home DVD player, but again wasn't recognized by the NEC. I then made the NEC the slave and the cdr the master. No luck. I put the master on the end of the IDE cable and the NEC slave in the middle. No change. If I put just the NEC as the only drive set as master and removed the cdr drive, the NEC wouldn't recognize a DVD or CDR and Media Player's DVD play option was greyed out. I followed the FAQ suggestion about making sure that DMA is enabled and that the 2 drives were recognized in the Device Manager. What's going wrong? Please make some suggestion. Thanks.
