I have had no problems with my ATV 160 on my 1080p Pioneer Elite plasma TV (PRO-FHD1).... I just bought a PS3 for that room and moved the ATV to another room which has a 720p Pioneer 5070 plasma tv. The ATV is sending a signal and I can watch my pictures, home moveis, etc. but when I try to play a previously purchased movie, it says there is an HDCP problem and will not play it. Any thoughts? Is there any setting change I need to make? All the connections are with HDMI. Shouldn't a purchased movie residing on my ATV play on a 720p plasma using HDMI? For bonus, any advice on how to use the PS3 to view my family pictures and movies would be appreciated. Cna it stream from my ATV or do I need to put it on a computer/HD somewhere? Thanks!!
