Serviio

You can watch many walla full videos episodes with the walla plugin
It does work for most nick and nickjr sites (not so well for the other prefixes.)

Examples:

More under nick.walla.co.il and nickjr.walla.co.il

It does work from UK as well (for those who understand hebrew )

Thanks for Olli for helping me with the code.
