OKAY HERES THE PROMBLEM
O.S. XP PRO \ SP2

4 GIGS DDR2 800MHZ

I HAVE A PIONEER DVD-RW DVR 112D I HAD ANOTHER DVD-RW HOOKED UP AS THE PLAYER BOTH HAVE THIS PROMBLEM.
THEY BOTH WORKED PERFECT BEFORE I TRIED TO COPY A DELL O.S. DICS WITH CLONE C.D. I HAVE UPDATED THE DRIVERS, UNINSTALLED AND REINSTALLED PLAYER , NEW FIRMWARE, AND WIPED CLEAN H.D. AND REINSTALLED WINDOWS XP PRO. , I USE NERO ULTRA , RAN THE SPEED TEST AND IT WORKED ON DVD+R BUT WONT RECONIZE OR BURN CDR'S

ANY HELP ANY SUGGESTION WOULD BE GREATLY APPRECIATED

THANK YOUWhat brand are the CDs and how old are they?

If both drives have the same problem and you have reinstalled the OS then it's either the motherboard or the discs. How are they inserted into the motherboard? Are they on the same channel?the dics are new I have tiied 2 brand names imitation, benq cdrs and the drives were hooked up 1 thru ide and the other usb 2.0. the mo\bo is a asus m2n-e Correct me if i'm wrong but DVD-R drives cannot read CD's, can they?

For example with my CD Drive, it has a DVD icon and a CD icon, meaning is can use both.

I have another computer with a DVD Drive and a CD drive (seperate) and they can only read what they were designed to read.I've never heard of a DVD drive that can't read CDs (except maybe a failing one). It just doesn't make sense from a sales point of view to not include backwards compatibility.
Of course I can't rule out that such a drive exists... but I'd SAY it doesn't sound very likely.

Btw. the drive in question can read CDs.

But mikey25702 you say you have done a clean install of XP? Not just a repair install? Have you made any hardware CHANGES? Have you tried to reseat the power and data cables for the drives?Sure any DVD- rw can read and write to either C.D. or DVD . No I havent made any harware chages except remove the IDE drive and I even tried it one of my other computers and it still fails. Yes I have installed new cables but that did not help either . Yes I wiped the hard drive clean and di a fresh install still it does not work

Help !!! Newer drives have more than one laser in them for different tasks...remove the drive and swap it into a known working machine...if it does the same THING one of the lasers is dead and you need a new drive.
