How can I play video over my LAN? I have a Mythbuntu computer on my home LAN where I store all my music and video files.

I'd like to be able to watch video that is stored on my Mythbuntu computer on my Galaxy Tab 10.1. The videos are in a variety of formats and sizes. I understand that some sizes might be too large to stream over the LAN, but I think it should be within the ability of most hardware.

The Galaxy tab connects via wifi to the home network.

I have tried some apps that claim to be MythTV front ends, but they have proven to be difficult to set up in that they require a lot of MythTV specific settings.

I'm looking for a solution that is independent from MythTV, and just plays the video files in an independant player, much like I would open a video file on my desktop computer with VLC.

Is that possible, and if so, how?
AirPlayIt is one software solution that will stream video files from your computer or file server to an Android device. It simply streams things Android can play and transcodes things it can't.

Plex is another popular solution.
