I just updated my Samsung LN46C650 and now I can watch Netflix on TV. Great quality and convenience!!!
I hope they update the firmware on my 50" plasma purchased in Aug 09, but I am thinking they won't. No biggie, I have the Wii hooked up to it right now and the quality is good.
BTW, keep a daily tab on your bandwidth. For me, each hour show is about 1 gig.
