well I tried nspluginwrapper but once it came
to compiling nss I gave up.

so back to looking at the setup I have right now,
it seems either some of the commercials on hulu
are stack smashers, and some are not.
or there something else happening internally i.g.
I usually hit this error, then about after the second go of
if(after firefox exiting) movies start and work.
(I guess this teaches me to enable stack protection)


thanks for the response,
(ill just leave it as it is for now).
