Video streaming from PC to Android? I just installed Opera Unite's video streaming service. I can access my video files through my phones web browser (Galaxy S), but it starts to download instead of playing.

Is there a player I can use to watch streamed videos from my PC?
Non-root Option

Subsonic

Subsonic is a free, open source, web-based media server in Java. It is easy to install and runs on various platforms. There is also a Subsonic Android App, which allows you to stream audio and video from the server. Video streaming is done with Flash. You should disable transcoding for MP4 files, since Android's Flash Player can play MP4 native.

VLC Remote

Use VLC Remote. Instructions are on he homepage. While this is mainly a remote control app for VLC it's also able to start a stream which you can receive either also with VLC Remote or with any other streaming capable player. I suggest RockPlayer.
To start the streaming, open VLC Remote, connect to the VLC instance on you streaming server, browser the files and press long on the file that you want to stream. A context menu should appear, from where you can choose stream. 

Root Option

One option, that needs root, is to use cifs manager to mount the windows share with you video data, which enables other players to play the video as it was stored locally on your device.

Paid Option

This would be Plex.
