Hi, I have been able to watch Hulu on my Mac on our wireless network without problems or speed issues anywhere in our home. However, if I try to hook it up to our Vizio 48" LCD HDTV, the video lags and usually freezes. The Mac Book Pro is 4.1 running OSX 10.6.8 with 2GB RAM. I use a DVI to HDMI cable out to the TV. Video shows up no problem, but it is really slow and freezes. The moment I unplug the cable, video resumes on my Mac just fine. Any thoughts? TIA
