Set a program to record later, watch TV fullscreen on another channel (not the channel that the program to record is on). When the time comes, MP will switch channels automatically, however the OSD (press y) doesn't update, i.e. still shows the program details of the previous channel. Also the Rec symbol doesn't so either. You have to return to the My TV main screen, then go back to full screen before it will update. Also, when you return to the main screen, it rewinds all the way through your timeshifting buffer - you have to fast forward back to the current time.
