Hi I was in the guide on our 605 (but I'm sure this isn't just for 605s so I didn't post in that thread) and the guide at the bottom said to press the green B button for Minitune. I pressed it but didn't see anything so I looked at the SD website but it still doesn't make sense. It says I can see another channel in the little window of the guide without leaving where I am but when I do it then leave the guide its on the other channel not the one I was on before. So it just seems like any other time I use the guide and change to a new channel. What is it supposed to do??
