Hi Russel!
It might be worth checking, whether the mtx-changer script has the right permissions set. I believe it should be owned by bacula:disk.
I believe that the output after ERR: is what is returned by the call of mtx-changer.

If I am wrong, someone please correct me!

I am having problems labeling tapes.  I have a FreeBSD 7.0 system:

FreeBSD backup.utoronto.ca 7.0-RELEASE-p2 FreeBSD 7.0-RELEASE-p2

with a DELL-PV-122T 8 slot tape drive.

The btape tests work just fine. ( See the output below.)
When I run bacula and try to label at tape, I get the following
permissions error:

I'm going to write one record  in file 0,

We should be in file 3. I am at file 3. This is correct!

Now the important part, I am going to attempt to append to the tape.

btape: btape.c:1577 Wrote one record of 64412 bytes.
btape: btape.c:1579 Wrote block to device.
btape: btape.c:505 Wrote 1 EOF to "Dell-PV-122T" (/dev/nsa0)

btape: btape.c:475 Rewound "Dell-PV-122T" (/dev/nsa0)
Done appending, there should be no I/O errors

Doing Bacula scan of blocks:
1 block of 64448 bytes in file 1
End of File mark.
2 blocks of 64448 bytes in file 2
End of File mark.
3 blocks of 64448 bytes in file 3
End of File mark.
1 block of 64448 bytes in file 4
End of File mark.
Total files=4, blocks=7, bytes = 451,136
End scanning the tape.
We should be in file 4. I am at file 4. This is correct!

The above Bacula scan should have output identical to what follows.
Please double check it ...
=== Sample correct output ===
1 block of 64448 bytes in file 1
End of File mark.
2 blocks of 64448 bytes in file 2
End of File mark.
3 blocks of 64448 bytes in file 3
End of File mark.
1 block of 64448 bytes in file 4
End of File mark.
Total files=4, blocks=7, bytes = 451,136
=== End sample correct output ===

If the above scan output is not identical to the
sample output, you MUST correct the problem
or Bacula will not be able to write multiple Jobs to
the tape.

Skipping read backwards test because BSR turned off.


=== Forward space files test ===

This test is essential to Bacula.

I'm going to write five files then test forward spacing

Ah, I see you have an autochanger configured.
To test the autochanger you must have a blank tape
 that I can write on in Slot 1.

Do you wish to continue with the Autochanger test? (y/n): y


=== Autochanger test ===

3301 Issuing autochanger "loaded" command.
Slot 1 loaded. I am going to unload it.
3302 Issuing autochanger "unload 1 0" command.
unload status=OK 0
3303 Issuing autochanger "load 1 0" command.
3303 Autochanger "load 1 0" status is OK.
btape: btape.c:372 open device "Dell-PV-122T" (/dev/nsa0): OK

The test autochanger worked!!
