Can't get two LG burners to work at same time

[supirio]

Problem: Only one drive will work correctly at a time. I successfully burned two cd's at the same time however if I put a CD/DVD in one drive, it will read the contents fine. If I then try to use the other drive at all to do read a CD or DVD, it reads nothing, says "Please insert disc into drive D:" or "Incorrect Function". If I put a CD in drive 1 first, it will read it fine from that point on, but drive 2 is useless, or vice versa.

I have 2 LG GSA-4040b drives.
*updated firmware to a302 on both
*tried few different setups:
*one drive on secondary master, one on secondary slave
*one drive on secondary master, one on primary slave
*one drive on secondary master, one on primary master (sata boot)
*pentium 3.2ghz 512ddr asus p4p800d motherboard
*updated aspi layer
*one lg drive as secondary master, a DVD 16X Reader on secondary slave, same problem, both won't work at the same time can't do DVD to DVD
*tried one as PIO one as DMA, both as DMA

I've read of others with similar problems and no solutions (some suggested reinstalling xp altogether), any/all ideas welcome. Thanks

Update:

*It will read both DVDs if I boot up with DVDs in the drives, but after I remove them they go back to not reading anything.

*After a fresh install of Windows XP on a separate harddrive, removing all S-ATA drives and other Harddisks, it seemed to work, I might just have to re-install everything from scratch and hope for the best though I was really trying to avoid this.

Anyone have similar issues? I thought I had it licked when I changed a bios setting from [Yes] to [No] (Plug and Play OS) but didn't work like I thought =(

Final Update:

I purchased an external 5.25" Bytecc case, used USB 2.0 to plug it into the computer, can use both drives no problem, so problem solved.

Plus I have a mobile drive too, bonus
