I don't think so: the column itself is named "Info", not "info". The field generated uses the name of the column, as configured in your Wireshark preference file.
3) Some of my .vwr captures seem to only decode in tshark (with and without -V) but
don't decode with -2 or in wireshark (I'll open a proper bug for this once I have more
info). Btw, how can I convert .vwr files to pcapng? Both Save and Save As are greyed out.
