Apple TV Software 2.4 and "HDCP Off"

Try removing the HDMI cable and restarting the Apple tv and tv set.

Try taking the switcher out of the chain. Also, try a different HDMI cable.

I'm sorry... Wish I had more suggestions.

The fact that an HDMI cable will work in one particular set up doesn't necessarily mean it will work in another, have you any other cables you can try.

Are you still trying with a direct connection to the tv.
Have you tried pulling ALL cables and powering back up after 30 seconds.
Just to clarify, you said no HD works, do you mean no purchases work, HD content on its own shouldn't require HDCP unless it has protection.

HDMI is clearly the problem - probably the AppleTV HDCP implementation.

Your TV is presumably HDCP capable.

If you haven't tried my only suggestions would be to test with a different TV via HDMI, or with component on this set.

Also - if you have more than 1 HDMI input try them all, I can remember someone else's AppleTV working on the first HDMI input but not others.

Yep and in some cases where there is more than one HDMI port on a tv, the user has needed to change the name of one of the ports through the tv settings.

I don't fully understand why it's only HD purchases that have a problem, unless the SD doesn't have protection.

It may depend on how some TV's implement multiple HDMI ports - is each port given an indiviudal hardware interface, or are some effectively on an internal switch?

The odd thing of course is that it didn't do this before.

Agreed, but I find it just as odd that SD purchases seem to play with HDCP turned off.

I have the same problem and have tried the same solutions, including cable changing and unplugging and restarting AppleTV. I originally posted that I could not play Mad Men HD. Thursday, I bought and downloaded two SD episodes and they transferred and played perfectly. Over a year ago, I bought the cable recommended to play HD. Its seems to be the upgrade to Snow Leopard. I hope a software upgrade will fix this soon.

HDCP = High Definition Content Protection, is only affection High Definition Medis, The file itself, not the player.

It means that the HDCP encryption is in the file or on the Blu-Ray dics, etc, and it is passed on through the HDMI connection which is Digital. It is not used through component as it is analogue. This protection has been created to prevent copy on playback from HDMI whic is pure digital.

This is the reason why the SD work perfectly and I bet that if you connect component instead of HDMI, your HD rentals will work.

Some cheap switcher will not "pass" the HDCP along so this is why it is good to remove the switcher to do the test.

There is an "handshaking" between the TV and the player (ATV, Blu-Ray, etc) that occurs when turned on. I used to have a cable box that if I changed input on my TV while the cable box was ON, I had to disconnect the HDMI cable, turn everything off, connect the HDMI cable, turn the TV on first and then the cable box... I tell you HDMI/HDCP can be a real pain... I am happy with my Aquos TV and Apple TV, I never had any problem... Now I am thinking to buy a audio amp with HDMI switching...
