Ah, sorry about that, I mis-read it.

I think I can see the same problem now. I just tried to rename a
file.tar.lzma (which MC opened normally) to file.tlz and MC told me it
"doesn't look like a tar archive". However, when I manually ran the
command:

lzma -dc file.tlz  2>/dev/null | tar tvvf -

it listed the file's contents as you would expect. md5sum of both
files are identical.
