OK, try again by hand for this tape:

* rewind: mt -f /dev/nst0 rewind
* show header: dd if=/dev/nst0 bs=32k count=1
* go to next file: mt -f /dev/nst0 fsf 1
* show DLE header: dd if=/dev/nst0 bs=32k count=1
* IF the DLE header is correct (ie, no character substitution), then try and 
list what's in the archive: dd if=/dev/nst0 bs=32k|tar t(z? are your archives 
compressed?)f -
