I have to duplicate 4.x GB of mpeg2 files onto 30+ copies of DVD-ram, and being able to do it as UDF instead of having to format UDF on an NT box and copying the files before duping a disk image would save me at least one headache:) --- David To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

However to play/read/use DVD's you dont need UDF, they are also readable as an ISO9660, but that might change in the future... -Søren To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

I will at some stage also try make a UDF creation module for mkisofs as well. In the meanwhile you should be able to mount most modern DVDs using the ISO9660 filesystem as they should be "bridge" format, (in which there is metadata for both types of filesystems).

As for RO UDF, it is useful for reading UDF2.0.1 cds that don't have ISO9660 on them (I have one here). The experience of looking at how the other vendors do read/write (especially adaptec) in order to be able to read their disks will be used to make it writable. -Søren -- __--_|\ Julian Elischer / \ [EMAIL PROTECTED] ( OZ) World tour 2000 )_.---._/ presently in: Budapest v To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
Re: UDF (DVD fs)
Soren Schmidt had the audacity to say: Uhm, the real value of UDF is that it can be used as a "real" rw filesystem on CDRW/DVDRAM media, if this is not implemented the value of having UDF is very limited IMHO Not necessarily, since the cd9660 backward compatibility is not a requirement of the standard. I have Pulp Fiction here, and it doesn't work, because it has no 9660 compatibility. In the meanwhile you should be able to mount most modern DVDs using the ISO9660 filesystem as they should be "bridge" format, (in which there is metadata for both types of filesystems).
