Is Hulu really that lazy?

I hate you and claim hax.

Whenever I try to watch a movie and play maple/any other game, unless the movie windows is the active window, the picture freezes and I only hear noise and the movie only updates its showing frame when i A activate the window or B click

I wish I could game and watch..

That happens to me some days on some sites. Youtube is most notable but Hulu always works for me. Whenever i stream tv shows some sites do that while others dont. Im assuming it has something to do with the flash video files and maple/windowers
