I am considering buying the 2.4 Mini to stream to my 52" Sony LCD. I use Hulu, Netflix, Vudu, Pandora, and Amazon. I don't need it for bluray or DVD playback. I use a standalone player for that. Strictly for streaming. My connection is 20Mbps. Will this mini give me smooth streaming in 1080P? I have little tolerance for choppy streaming so i'm very interested to hear from people who utilize this function. Do I need to upgrade the RAM to 8Gigs?
