Yes, one of the possible solution would be to pass from the client
program (ethereal,tethereal,etc) to the wiretap, the type of the file
and the enconding of the file it is about to read and skip the
autodetection.
This could be implemented in the Open window or/and Capture window

Another problem:
I want to capture from a named pipe or stdin ("ethereal -i -"). It works
ONLY if the data from stdin or pipe is in libpcap format.
If I want to live capture from a pppdump trace ( tail -f /pppdump |
ethereal -i - ), it does not work.
