Is anyone out there a hulu.com user? Are you having issues with playback in the past week? Playback has been choppy, slow, and without sound for a week now here in the land of my ibook. I've upgraded to a super fast roadrunner connection, have plenty of hard drive space, and can watch other video sites like utube and abc.com. I've also tried using not just safari, but firefox and internet explorer too . . .
