Splashtop Remote Desktop is a android app that brings your computer to your Xoom tablet, featuring full video and audio support. The app needs a PC and looks like Play-ON but there are NO monthly charges after purchasing it.
I am using it to watch Hulu, Netflix and movies on my Xoom. The streaming quality of netflix is smooth and impressive. Splashtop seems to only work for local networks.
