I recently got a new Liteon 52x24x52x cd-rw drive and it initially worked
flawlessly. I'm currently on a spindle of 40x certified media, and the
drive, while refusing to burn at 48x or 52x, always burned at 40x. However,
suddenly I find that on the same media, it refuses to burn at anything above
16x. My other liteon burner, a 24x drive, has no problem burning 24x on this
media.

I'm not sure what's happened here. I did flash from the 6S0D firmware it
came with to the 6S0F. I'm not sure if the change in burn speed occurred
with the flash or not, but it's currently my best guess. However, after
managing to find a copy of the 6S0D firmware, it refuses to flash my drive
as it claims to be compatible only with liteon drives containing pre-6S0D
firmware installed.

Is there any way to downgrade my firmware? Is there any other explanation as
to why it suddenly doesn't like my 40x media?

My Lite-On 52x24x52x cd-rw drive is acting the same way yours is. Mine is
older, bought in January 2003. The Firmware revision is 6S08. Odd that it is
not in the letter sequence you mentioned. Since I have not made any changes to
the firmware, I can't attribute the slowness to that. But for now, I am using
12X (Maybe 16 would work) for my CD-Rs.

In one of my work machines, I have a Pacific Digital (relabeled Liteon
LTR-48125W) 48x12x48 burner. At first, WinXP refused to talk to it in DMA
mode, so burns were slow and hogged the processor. I found a utility to
apply Liteon firmware updates to it...the first one was the latest available
at the time. I still didn't get DMA from it. After that, I "downgraded" it
to VS0D and now DMA works.

The same machine also has a (retail-boxed) Liteon LTD163D DVD-ROM drive.
Updating that to the newest firmware killed DMA. "Downgrading" it back to
GHR3 restored DMA.

I suspect that the recent firmware "updates" are breaking more things than
they fix. If you do a little searching of the firmware sites, you should be
able to find the software that lets you force-apply any Liteon firmware to
any Liteon (retail or rebadged) drive. I'd name names, but I deleted the
software and firmware files after getting my drives working properly.

(If it makes any differece, the machine with these drives is a dual Athlon
MP 1900 on a Tyan S2466N-4M, running WinXP Pro SP1. Running the
Microsoft-supplied IDE driver or the AMD 768 IDE driver made no difference.)
