I have a MacBook white, when I watch Hulu Desktop full screen, everything is perfect. If I connect my MacBook to my TV through a Mini-DVI to DVI adapter connected to a DVI to HDMI cable and I tell my Mac the TV is a second monitor and move Hulu Desktop to that screen and put it full screen the video stutters to be unwatchable. If I just mirror the display and set Hulu Desktop full screen, everything is fine. Any ideas why this is happening?
