yep, done that (always do), but no change.
to reproduce,
in ioninja.cfg (commented out)
set ioNJ(exec_on_complete) {
#{/XXX/|/TV/|/MOViES/|/CiNEMA/|/x264/|/XViD/} {TCL ../scripts/ioninja/plugins/unpack_complete.itcl $args}
in unpack_complete.itcl
set ioNJ(UNPACK_TO_PATH)
{/x264/} {} {1} {1} {1} {0}
then run "site rescan" in a rel. in x264 section, it then will try to unpack. if i # the {/x264/} {} {1} {1} {1} {0}, it doesnt.
