Hello just registered to see if anyone could help me out.
I've read some posts with same problems, tried every fix suggested, still no luck.

I bought a Samsung: SH-W162C DVD burner,
few of my problems:

1: when updateing firmware, i get error "Flash cmd fail!!" the drive came with 09 on it (tried to get to 10). so i'm not sure if i really need to worry about that now

2: when burning (nero express 6.6.0.15 that came with drive) i get "Buffer too large" (i have a log file if anyone wants too see that)

I can burn CD-R's fine. those errors above are for DVD-R's.

my system:

OS: windows xp SP2
mobo: Chaintech 7NJS Ultra Zenith (with updated nvidia chip drivers)
4 hard drives: 2 with IDE cables (80 gig, 100 gig) and 2 with serial ata (80 gig, 120 gig)
1 dvd burner/ master /ide. (the drive im asking about)

Ive tried to set the drives to DMA mode, with no luck. in my bios everything that says DMA is enabled, and the PIO are on auto. no disable, only Mode 1-4
also i cant change the modes within windows (no advanced tab, like noted in other posts ive read)

----------------------------
so the DMA is off for sure. not sure what to do now. all my hard drives are full as hell. want to clean some of it up, and i want to avoid using 500 or whatever CD-R's.
