My NEC3500AG (V2.18, firmware Liggy & Dee V2 beta 3) burns fantastically (note1) . But, ONLY when burning with Nero6.3 a FULL Princo DVD (4x), appears a very narrow/dark/unreadable ring near the outer edge (3.4GB or 4GB point).
(note1) For example: Ridisc (-R), Verbatim (-R, +R, +RW), Ricoh (+R, +RW) and crappy media like Princo (-R). Medium to very low PI/PIF, depending on the media quality. All readable discs .Main tester Nero CD/DVD Speed 3.55.
The case is that previously creating an ISO image (> 4GB) and burning it with DVD Decrypter 188.8.131.52, e.g., using Pattin-Coufin ASPI layer instead of Nero folder Wnaspi32.dll, the ring DOES NOT appear in those Princo discs. Moreover, burning those Princo discs using another writer (Liteon 811s, higher PI/PIF) and Nero, the disc DO NOT show the dark ring. Only shown combining NEC+PRINCO+NERO, get it?
My [healthy] system: AMD Athlon XP 1700+, 512MB DDR, 120GB & 160GB Western Digital HD's, frequent defragmentation, DMA on (of course ), no other application or 'tray icons' when burning, etc, etc
My system / Nero burning normally does not show any buffer underrun, but maybe there is something with the abovementioned combination. Something is happening. I suspect of some bug/drawback of the new Nero ASPI layer, Wnaspi32.dll (version 184.108.40.206, december 2004), but not sure.
Well, any idea / info/ suggestion / explanation / request for more info... welcome.
By the moment, I will follow my self-recommendation of burning these few Princo's (only for experimenting, common sense is buying 4x Verbatim and Ridisc, beautifully burnt @8x and beyond) through ISO - DVD Decrypter, achieving PI around 250 and PIF around 1-2
Any comments appreciated.
