I am having very annoying problems with my Lite-ON SOHW 1673S (Firmware JS05) - it will not keep up to a disc at any speed when burning a DVD on the fly from my SAMSUNG D162C TS02 DVD-ROM - I am currently trying 8x and it takes over 30 minutes to complete.
The drive buffer is all over the shop on nero 6x and is constantly under-running. I know there are common fixes for this problem and believe me, I have spent hours searching forums for solutions but come up with nothing.
Here is a list of what I have tried:
DMA - DMA is enabled for both drives and windows XP is not reverting to PIO mode. I tied re-installing the IDE drivers but nothing (deleted and restarted windows). DMA still active. Tried PIO, and as expected, extremeley slow, even compared to what I am getting at the moment!
My DVD-ROM was playing up, originally had brand new LITE-ON ROM, so swapped it and now have above drive to read discs, this did not solve problem).
I have tried my friends DVD writer - Lite-ON (1653 I think), doing the same thing, even though that is a known working drive, so I guess it can't be the drives themselves.
I have tried different software - roxio easy media creator 7, just as bad. Tried a free DVD copying utility, exactly the same buffer behaviour.
I have tried an earlier version of NERO - just the same, I have also tried installing every update from the site, just as bad.
I have updated the firmware on the writer to the latest version, still the same.
I have 80 pin cables installed.
The writer burns perfectly at full speed when burning from an image off the hard drive.
My machine is well within spec - AMD Athlon 2500+, 768MB RAM. The windows XP task manager performance tab shows the CPU idle with 2% used at the most, so my system certainly is not straining for resouces.
I have updated the IDE SiS drivers, just as bad, however, this showed me something which may be of interest - the IDE utilites tool says that the current device use is UDMA 4 - I thought this particular drive only supports mode 2? Could this affect it? My DVD-ROM is running at UDMA mode 2.
If anybody can come up with an answer, I would be very grateful - I may even ask for a photo and stick it next to my writer for anyone who solves this as I am running out of patience!!!
