Yes, you are right. Everywhere that I look, CD-RW and packet writing
and UDF file system are linked.
Things like cdrskin and mybashburn make no mention of udf.
I see in Ubuntu udftools which seems to offer needed utilities. I
further note that K3b appears to handle UDF but with no mention of
packet writing, this is in the Wikipedia entry. but I find nothing on
the K3b site, and anything I google (or bing) is either old and/or
related to burning large files. In any case udftools appears to put one
back at the command-line age, nothing wrong with that but nothing wrong
with modern conveniences either.
Maybe I should not be using CD-RW as my investigations indicate limited
shelf life of these disks, but that is a seperate issue.
I will follow this further, see my posts to the other respondents to my
original post.
thanks so much
Anne
