Experiment: Pico-ITX as Hulu Client

I tried a little experiment tonight.  I wanted to see if my Artigo Pico-ITX machine could act as a Hulu client.  I cleared off the machine and installed Ubuntu 8.10.  After installing the flash plug-in for Firefox I pulled up Hulu and loaded a 30 second clip from Family Guy.  The audio was perfect, but the video was very choppy.  I checked the resource monitor and the CPU was just getting hammered.  I guess I'm a little disappointed that even with a 1GHz processor and 1GB of memory, this little machine can't display streaming video.  YouTube suffers from the same stutter.  This is unfortunate, as I had hoped to connect this box to my HDTV as a quick and dirty web video streamer.
