I just bought two media players and set one up in my room on an old rca tv and it works great. i switched it to the kitchen philips tv and and none of the files have sound. then switched to the 52' rca rear projection tv with dvi and still no sound and no hdmi video at all. i updated the firmware to p70r2 and the sound worked. shut it off over night and turned on in the morning and no audio again. I changed all settings and tried resting and everything I can think of. Problem is the same with both media players, works great on the old rca tv but not on the philips tv or the big rca tv. I have hooked the audio jacks up to my reciever and just speakers and nothing. I changed the firmware to 3 of the most recent releases and still nothing, but both work on old rca tv????
