Roman Haefeli recently released two very handy shell scripts that let you watch and record TV through Wilmaa. All you need is mplayer and rtmpdump and, voilà, TV with hardware-acceleration, without any of the annoying and slow Flash player crap that Wilmaa throws at you.
This allows even slow computers such as netbooks to smoothly play these TV streams full-screen.
Check it out at http://github.com/reduzent/watchwilmaa
The script is released under GNU GPLv2, if you fork the project on GitHub and send pull requests for your improvements, I’m sure Roman will merge them.
Caveat: It might only work from Switzerland for now, I don’t know which countries can get Wilmaa.
