Q: Can't read a DVD formatted as UDF

I have a problem with my Windows 7 ultimate.

When I put a dvd-r disc formatted as udf to my dvd drive and go to My Computer, I can see that 3GB of data are on DVD, but if I clic on it it is empty.

In Disk Management I can see a partition on the disc, but in RAW format.

The hotfix support.microsoft.com/kb/975617 didn't install.

The version of the udfs.sys is 6.1.7601.17514.

On the *SAME* machine and DVD reader, under a virtual Windows 7 (Virtualbox), with the *SAME* disc, in Disk Management I can see a partition on this disc in UDF and can be read with success.

The virtual machine is made with images on ModerUI.

The version of the udfs.sys is the same: 6.1.7601.17514.

I don't have any burning software on the phisical machine.

I have also installed the same release of VirtualBox under the virtual machine, to see if this software can create some problem: no, the disc is always in UDF format and can be read with success.

Can anyone help me?

Many Thanks
