Plex

This software is pretty sweet, TBH. Allows mobile access of music and video files, even over 3G. Processor intensive but worth it if you want to see a show and you aren't at home.

Was streaming House in 720p yesterday. Looks utterly flawless on my phone.

It's been around for a while... there's even hacks to install it on Sammy Smart TVs... it's solid software, but I prefer my Slingbox since it doesn't require installing anything on a pc....

I downloaded this about a year ago but was mainly using it on my Google TV. Looks like they've upgrade the capabilities with myPlex significantly, now I can stream to my phone and tablet. Awesome!
