I am having the same problem. I never thought Linux would come between me and a pair of Yankees tickets.
Anyway, just as the OP I can play flash videos and just about everything else fine, but stubhub.com does not work. I am using the 64-bit plugin, and perhaps I'll try out the 32 bit one as well.
I am just posting to see if anyone has any updates.
BTW, I didn't realize this was in a Slackware forum. This problem appears to not be distro-specific as I am experiencing the same issue with Fedora 14 x64.
