The inputs on the front panel output the same as the back panel. So in the event you hook up your camcorder to them or a gamecube like I did, you watch and listen to those signals. You just have to switch to that input. They put front inputs to make it easier to hook up temporary devices like camcorder, portables, games, etc.
I think Pres-Sean may have answered the question, but my original question is once those inputs on the front are connected as you described above which corresponding output on the back will they play the video thru? (ie dvd, tv/sat, etc) Thanks, I know this shouldn't be this confusing but for the life of me I cannot find this info in the owner's manual.
