[Ethereal-users] tethereal display filter question

["Romel Khan" <rkhan@xxxxxxxxxxxxx>]

Seems like display filter from tethereal doesnt work like it would from ethereal. In fact nothing other than basic filtering works. Any suggestion appreciated.
For example:
 
 C:\Documents and Settings\rkahn\My Documents\trace\bxIssues\Oct7>tethereal -r Oct_07_104558.log -w temp ip.src==66.33.157.18&&udp.srcport==5060||ip.src==66.33.157.18&&udp.srcport==6070
No log handling enabled - turning on stderr logging
