The point is when you change those channels a lot of actions have to carry out: first of all, input is stopped and then decoder and other modules are removed. After that, demux, access and network modules have to be initialized, and then decoder is opened and starts buffering, audio modules are initialized and so on. Due to this, changing between channels takes some time and some effects (black and frozen screen) appear.

This sounds like a great idea. I am looking forward to your patch.
