I was wondering if it would be possible to add a video stream from a webcam as a feed through my linux box to my tv (likely as an extra channel) usind a mythtv or freevo setup So that when I'm watching tv in the basement and the doorbell rings, I can switch channels to my webcam channel and so who it is!! Maybe with picture-in-picture, the webcam can be motion activated to pop-up a pip of the webcam!
