It's quick (to install), it's far from being unpolished. If you ever wanted to watch videos on your tablet, I'd highly recommend Knots.

It's the only way of video streaming I have tried, but my impression from the other method discussed here is that you'd have to manually start streaming of one particular video on the PC first and then you can watch it on the Tablet. The difference is that with Knots you can request any video from your PC/Mac to be streamed on demand (now with WorlTV99 streams too). Oh and with Knots you only have to use the command line once to set everything up.
