I tried it and it works to some extend. bzip2 dies at the end and in 
some cases the last file in the archive is not restored correctly. I've 
been padding the tar-bziped file with zeroes up to the next 32kB block 
boundary and that seems to work. The restore command still returns an 
error at the end but the restored files seem ok, at least in the few 
attempts that I made. The same behaviour (tar or bzip2 dying when 
reaching the end of the media) seems to happen as well on floppy disks. 
Anyway, using ext2 on DVD is probably the way to go for Bob.
