Hi Robert,

Although Ed has given you a response, I'd like to add the following.
UDF.IFS is a *standalone* packet-writing method for optical-media.  
AFAIR it marks out 32KB-blocks on the RW-media when formatting, which 
allows for "random" reads/writes.
You cannot "mount" a re-writable drive under RSJ, then try to use 
UDF.IFS with it!
RSJ doesn't use packet-writing! If you want to try UDF.IFS on a system 
with RSJ installed, you'll first have to disable the RSJ statements in 
the config.sys, in order to do so.

HTH
