After beeing so frustrated with the DVD writing results of my LiteOn LDW-811S and after i had seen many people experiencing the same problems with the drive i decided to get a NEC 2500A, which is said to be one of the best DVD burners available. It arrived today and i installed it as Master at the secondary IDE-channel (Slave is the LiteOn which i still need to burn CDs and to test DVD burning results with KProbe).
Stock firmware was 1.07. I immediately flashed it to Herries 1.07 v2 Beta 5 with DL support using the Windows flasher. I then bitsetted the drive to DVD-ROM booktype using the latest DVDInfoPro.
First some information about my system:
Build time: December 2000
AMD Athlon Thunderbird 1Ghz
Windows XP Pro SP1
I burned the first DVD (4.22GB movie), Ridisc 4x DVD-R (RITEKG04) using Nero 18.104.22.168 (latest). I then scanned the disc with the LiteOn using KProbe 2.22 and surprisingly the results were almost equal to what the LiteOn had produced before. Burned another Disc (Verbatim DLP DVD-R Pastel Color (TYG01!)) with the same configuration and the same movie. Again the results are almost the same. Look at my scans and remember these are TYG01 media burned at 4x speed!
I really donÂ´t know what to do now. It canÂ´t be the burners IMO. Nero CD/DVD speed Burst rate test showed 25MB/sec for both drives. I used many media and the results are the same so it isnÂ´t a media issue either. The only thing i could think of is buying a new IDE cable (remember my system is almost 4 years old now) as the scans somehow look to me like a data transfer error (notice the many high spikes).
OK, this is as detailled as i could do it so please, i need some advice now.
Thanks in advance
The first scan shows the LiteOn results, second one the NEC results.
