Windows 7 - HP DVD drive won't write DVD's

I bought a new HP1260t DVD RW, and it will not write DVD's. It has not from the start. It writes CD's just fine, but I need to start saving files from a video camera, so I need DVD size capacity.
It reads both CD's & DVD's fine.

Device Manager shows it as HP DVD Writer 1260t, and says it is working properly. Location is 0.
The error shown is "Problem Copying" "Windows encountered a problem when trying to copy this file. What do you want Windows to do?"

In Driver File Details, these are listed:
C:\\WINDOWS\system32\drivers\Afc.sys
C:\\WINDOWS\system32\DRIVERS\cdrom.sys
C:\\WINDOWS\system32\DRIVERS\imapi.sys
C:\\WINDOWS\system32\DRIVERS\redbook.sys
C:\\WINDOWS\system32\storprop.dll

Am I correct in assuming that only the .dll is the driver?

Windows XP Pro SP3
Memorex DVD+R

I also have a Sony CD-ROM CDU5215 installed (as drive D, and have no problems or conflicts with that).

Thanks in advance for any help. :-)

My drivers are cdrom.sys, imapi.sys, redbook.sys, storprop.dll.

The Afc could be Arcsoft ASPI shell. And that could be a hint why
your DVD does not work. You have some software installed, which
could be fiddling around with the software stack or registry.

Using the free Nero InfoTool, I see these tick boxes.
This is how I verify my drive is a DVD writer. Imgburn
can do this too.

There is a fixit for UpperFilter/LowerFilter problems. The
fix is careful to only apply it to the responsible GUID. If
you do the fix by hand, some people manage to delete the
UpperFilter entries for every GUID they can find, and that
disables the keyboard.

You can try using imgburn, which is free, and has all sorts
of information about an optical drive. it is mainly oriented
towards converting an image file into a CD. The built-in
WinXP burning capability, allows drag and drop of files.
WinXP did not start with a capability for doing that to DVD
drives. And then, a third party tool would be a common
solution.

Imgburn

Mode : Discovery
Tools : Drive : Capabilities
Tools : Drive : Check For Firmware Updates

The latter option is not likely to work for you, but that is just
an example of some of the things it can help with.

The issue could be an UpperFilter placed by Arcsoft, or
it could be the ASPI driver that is somehow responsible.

Generally, burning tools provide their own ASPI, if it is
needed. At one time, people would spend hours working on
that, but that has never seemed to be an issue on WinXP
here for me. So I will have to assume it is a "do not touch"
issue.

You can try uninstalling Arcsoft, if that is what put the
Afc file there. I would not try removing it by hand.

If you can find the Afc file on your C: drive, and do "Properties",
you may be able to determine the provider of the file, and see
whether it is Arcsoft or not. Arcsoft makes many software
products, so I cannot guess right off hand which one it would
be.

Thanks, Paul.
The Arcsoft software was indeed put there when I ran the installation
CD for my Toshiba HD camcorder.
Both the DVD writer & the camera were purchased & installed around the
same time.
I have noticed that mp4's taken by the Toshiba camera do not seem to be
recognized by Windows Movie Maker, so maybe there is something
propietary going on. Dunno. I will try uninstalling Arcsoft.

Thanks again! :-)
