I'm not absolutely sure, but I think I remember you don't use j or z for making an archive. The gzip and bz2 filters are for extracting .tar.gz and .tar.bz2 files.
Try this
tar cvf <filename>
bzip2 <newtararchive>
result
filename.tar.bz2
Now
tar jxvf <filename.tar.bz2>
decompresses and untars all in one.
