Have you tried pausing it to let it load? I didn't watch the whole episode, but checked out 5 minutes to see if I had the same difficulty. I didn't. The only thing I can suggest is starting it, then pause for buffering time.
Barring that, check out http://vip.tv-video.net/index/index.html#
To watch for free, check out the weekly quiz here: www.friendvista.com/forum/viewthread.php?tid=3080&...3D1
and you'll have enough points to watch at least 5 episodes. There's no illegal downloading and it's good viewing quality. I'll look for you if you can't get your Heroes fix anywhere else. :)
p.s. I have the same username there as here.
