First, let me thank everyone here at the cdfreaks for maintaining such an excellent site!
Well, I purchased my NEC-2500A from NewEgg after reading posts and reviews on the Fatwallet several weeks ago. Since then, I have burned several dozens of movies on 4 different brands of dvd-r, first x2 discs than x4 discs. They all play well on three of my stand alone players. However, I realized that 60+ minute burn time on x2 did not improve on neither of the x4 disc brand (memorex & imation) I purchased recently. Being new to the DVD burning, I thought it was my PC (P4 2.4Ghz with 533Mhz fsb and a pair of PC3200 512MB RAM running at 333Mhz) but from what I am starting to learn, that doesn’t seem to be the case. It has XP Home and I am using the latest Nero Ultra and DVD Shrink.
After reading the troubleshooting guide along with few other posts, I changed the NEC drive from a slave to master which seemde to take the burn time down to around 45 minutes on x4 burns which does not improve using the x6 burn settings (memorex). I also made sure DMA setting and the Transfer Mode is set to “DMA if available” on both the primary and the secondary IDE channels. However, “Current Transfer Mode” shows “PIO Mode” on both. I’ve trid to uninstall the IDE channel NEC-2500A is on (primary) but when the PC in rebooted, window reinstalls to return to how it was before. I also flashed the original 1.06 fw to Herrie’s beta 7 (THANK YOU!!! ) but burning Memorex disc at 6x speed still yielded same burning time of 45 minutes.
Next thing I want to try is enabling the “EDI mode” in the Bios as someone had suggested before. Can someone explain to me how this can be achieved? Also, is there another way to uninstall the IDE channel? I am so lost on this…
Thank you in advance for your help on this matter!
