Problem with LiteOn SOHW-1633S (Slow Burn)

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:

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?
