The taste-plugin allows to disable specific broadcasts by given keywords. When the channel is switched and the broadcast there comprised the keyword, the new channel is blacked out and an OSD message is shown. Also it is switched to the next channel.
Keywords can be added in the setup. If the current broadcast is unenjoyable there exists a fast way to add it to the keyword list.
