[Dvdrtools-users] Mkisofs UDF support.

[Richard Scobie]

I have successfully created and am able to mount an ISO9660 DVD-RW disc, 
created on a Pioneer A-03.

However, when I try to make a UDF disc,

mkisofs -o backup.udf -U -J backup/ or
mkisofs -o backup.udf -U backup/

it burns OK, but I am unable to mount it

address@hidden rs]$ mount -t udf /dev/cdrom /mnt/dvd/
mount: block device /dev/cdrom is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
       or too many mounted file systems

I have UDF read/write support in my kernel (2.4.18) and am able to mount 
 DVD video discs that have been created on the same drive under Win2000.

I am assuming this is because, as mentioned in the mkisofs man page, 
"UDF support is currently  in  alpha  status", but I just wanted to check.

Given that I am primarily looking to archive data to DVD-R media, what 
are the limitations of Joliet ISO9660 (the disks need to be Windows 
compatible), that I need to watch out for?

Thanks for any assistance.
