When watching a recorded show if going through the menus you will have to press back a few times to get back to full screen. If you press TV it takes you out of the recorded show and back to live TV. Would it not be better if TV would take you back to what you were watching then if pressed again on full screen it would take you back to live TV.
Also when setting up a series link I've found that it ill set it up but you have to go into it again to be able to change the settings. It would be nice to be able to enter settings as you start the series link.
