Try Adobe AIR if you have to work with SWF files. Otherwise, on a similar question, Valentin from Direct-l list had suggested
http://hollywood-mal.com/
As a programmer, I found Hollywood MAL a very good alternative (in some places, even better) to Director. We could not move to it because we have developed a lot of e-learning content using Flash SWF and Hollywood MAL does not play these files.
Hope this helps.
