start your movie then after 5 mins or so press "X" and it will minimize but keep playing the movie. Press the "back" button once and it will return you to the main options screen with the movie playing in the background. Select settings but don't press "A". You will see information come up that says System Info and it will give you your ip address and your two temps. Should look like this more or less Press "X" to enable full screen again and "X" again to minimize the movie. This way as soon as you press "X" you should be able to see your temps if there is any difference running at full screen compared to running minimized. Check your temps like 3 times in 5 min intervals. You should also stop the movie completely and see what your idle temp is.
