What was the exact command you used to produce the file?  The ".txt"
makes me suspect it's a text file, not a snoop file.  To use "-F snoop"
with Tethereal to produce a snoop file, you also have to use the "-w"
flag - if you run Tethereal without the "-w" flag, it just produces a
textual dissection of the packets, not a binary packet capture file that
Ethereal or Tethereal can read.
