And I don't think there ever be a stream recorder that will record videos from Joost. There is only one service that uses this proprietory software to deliver TV content. If someone releases a stream recorder for Joost, its developers can easily make a small fix and force users to upgrade the software. The life of stream recorders for such services is way too short and there is no sense to develop them.

I don't like services that limit my rights. If I can record my local TV broadcast freely, why should I use any IP service that doesn't allow me to do the same?

If you like Joost I suggest you to keep bugging the developers to offer recorded programs to be downloaded as well. Otherwise switch to other services that have such an option.
