I have been using the LiteOn SOHW-1633S with DVD shrink. At first, everything was great, but now its taking a lot longer to scan and burn. Any help would be greatly appreciated.
try with a new firmware: http://codeguys.rpc1.org/firmwares/1653S.CS0M.patched-cf-ledfix.rar
is your dma enable?
as toant103 said, your dma is not enabled, or has been disabled by mistake.
this happens a lot here, especialy when i update firmware without rebooting (just hibernate).
My DMA is enabled. Also, I have not installed the firmware suggested. Forgive my ignorance; are there any dangers associated with installation?
