DVD Recording/Image mounting problem

[nergal]

Hi,

I got a serious problem with my Windows XP SP2 (32Bit) OS. I just
changed from Windows XP 64Bit due to some problems. Now I cannot burn
DVDs with my DVD recorder (it completes the recording session but is
empty when I try to read it), but I can record regular CD-R. The same
problem exists for virtualization of disk devices, like Alcohol120%,
Daemon Tools etc.
I can mount regular CDR iso files with e.g. Daemon Tools, but DVD iso
files can be mounted but not read. The following error is displayed
when trying to read a mounted DVD iso from the virtual device:
"Windows cannot read from this disk. The disk might be corrupted, or
it could be using a format that is not compatible with Windows."

This worked with Windows XP 64Bit. And I also use NTFS (of course) so
it's not the FAT32 limitation, though it seems to be a limitation
problem with big files?

I googled _alot_ for an answer and I havent found an answer, only a
lot of people having the same problem.
What should I do? Re-install Windows and hope for the best? Repair the
system?

The CPU I use is Intel Core 2 Duo btw. (Should'nt mather?)

Best Regards,
Nergal

Should also be mention that I have a regular CD-rom as well. But I've
tried to remove both of them and still I cannot read from the mounted
ISO files. So it shouldn't be anything to do with the DVD/CD devices.
