"Linux/Unix+Windows" formatted DVDs burnt using K3b are unreadable in Windows

I burnt a couple of DVDs using "Linux/Unix + Windows" as the filesystem, but
they could not be read in Windows.

In both Windows Vista and Windows 7, they showed up as unlabelled blank disks.

In Ubuntu Oneiric, they did not get detected by udisks, due to a udev bug[1]
where ID_CDROM_ID_CDROM_MEDIA_TRACK_COUNT_DATA was not set by /lib/udev/cdrom_id
for the burnt disks, but they could be mounted manually, and blkid showed the
the label and filesystem (iso9660) correctly.

Switching the file system to UDF when burning DVDs seems to solve the issue, at
least with Windows. I have not tested this with a CD-R though.
