Hello all, I am new to the community and this is my first post.
I was experiencing the same problem with Hulu player not finding flash on my media directors. I downloaded the flash .tar.gz and extracted flashplugin.so to /usr/lib/mozilla/plugins/ and renamed it to flashplugin-alternative.so
Modifying ~/.huludesktop did not work as it gets overwritten when hulu is started.
Hope this will help somebody.
