OK, never seen hulu, but googled it and looked at a clip
This clip displayed smooth, no evident loss of frames.
I also have to say, I'm using Solaris SXCE nv104 on my laptop. My laptop has Nvidia Quadro FX1600M graphics card with the Nvidia 177.82 driver.
I also right clicked in the video image and configured settings for hardware acceleration, and gave permission for them to store 10 meg or more (I believe this is buffering).
