I use 11.0 with KDE 3, but had this problem also with 10.3. I have a DVD with ISO9660 filesystem that I can mount manually with -t iso9660 but not with -t udf. HAL does not automount it. It does not show up in sysinfo:/, not even if I mount it manually.

In contrast, my DVD that I can mount manually both with udf and iso9660 is automounted with UDF and works perfectly. How can I make HAL automount an ISO9660 DVD?
