Using UDF DVD on AIX 5.3

I was trying to copy a 2.5GB mksysb onto a 5.3 lpar to add as a NIM resource. The DVD mounted fine but I could not see any files within the mount point. I thought the media was bad so I tried again with a DVD-R disk but the same thing happened.

I decided to split the file up into 1024MB chunks and burn onto an ISO. This worked fine so the problem must be with the UDF format.

Has anyone successfully written a >2GB file to DVD in UDF format. I suspect there may be a patch for this but I'm not sure where to look.

Thanks,
