Burner no longer reads DVD+R

I have had a Liteon 411S for several months and have successfully burned a number of DVD+R disks. I have not used any DVDs for a couple of months and yesterday when I tried to read one I had burned previously XP would not even recognise a DVD was inserted.

XP still reads and burns CDs okay and will play a commercial DVD, but I can not get any DVD+R media (blank or burned) to be recognised.

I am on XP sp1 and am using Mirror Platinum DVD+R disks. I have DLA enabled and also have Nero 6.0 installed. I'm pretty sure this is software related, not hardware, but can't work out what. I have run ForceASPI but no difference.

Any help would be appreciated.

DLA and Nero are 100% incompatible- DLA will not mount any media, blank or not, if Nero is installed- just consult the DLA FAQ.

DLA as well as most packet writers need AutoInsertNotification being turned on. Did you happen to disable it?
It will also not work, or give blue screens with Intel Application Accelerator being installed. Oh, and finally it DOES need DMA enabled.

The drive is set to notify me when media is inserted and it does so for CD's, I am only having problems with DVDRs. DMA is enabled and I don't have Intel AA installed.

I am wondering whether one of the installed files has been overwritten but I can't find the install disk to re-install it. The software that came with the drive is Sonic DLA, is there anywhere I can download an install set? The Sonic site doesn't seem to have one.

I've uninstalled all DVD related software and cleaned the registry and have then installed just the software which came with the drive. It still doesn't work, all that happens is the drive chugs for a while and then stops. It doesn't see any media.

Does anyone have an idea what the problem could be?

The above utility might help... it seems that your udfs.sys native reader driver is not currently registered properly. Can you report the udfs.sys driver version, plus your actual service pack version and language?
