Not sure if it was only HBO but during channel changes I have had some black screen blinking issues then a message will pop up about the TV not supporting the copy protection then the receiver changes the resolution output to SD. But then the DirecTV box would see that my TV was in fact HD capable and would change the resolution back to native.

Last I heard the official fix from DTV is to connect via component video. Aren't you glad you played the game by their rules and talked your client into HDMI?

I believe the blame is on DTV, with a recent FW roll out.

I spent the day this week with one of the AMX/Autopatch techs going over AMXs new DGX switchers. He said Sony TVs have been causing problems with authentication because they take so long to complete the hand shake process.

He did not get into the full details only that the Sonys were one of if the the worst offenders and they(AMX) were trying to work out exactly whet they need to do to fix the problem on their side.

This may be the case with older or lower end models but this set is lightning fast and as stated above authenticates every time. its in the Constant re-shake that something skips and again (Only on HBO)

Well considering that it was a brand new multi million dollar house with a $60,000+ Dollar HDMI Matrix. I doubt it is either a older or lower end model.
Plus they have had several of them do the same thing.

I just read through a bunch of threads regarding HBO and DirecTV.

I got a call from a client today asking me if I could meet the DirecTV Service Tech at his house to help troubleshoot the problem. When I arrived the Tech began telling me everything he had done so far to try and figure out why the TV (new XBR - Couple months old) would flash the picture (go black for a half a second)
It looked like a very short HDMI handshake kind of thing that would happen in no specific pattern. Sometimes every couple seconds and sometimes every five or ten minutes.
This all started when the customers original DirecTV receiver took a crap and they installed 2 new HR-24s in his house a couple weeks ago.
The tech switched those boxes and the box with the problem acted fine on the older TV while the box from the older TV picked up doing exactly what the other one was doing.
I removed everything from the system except for the HR-24 to the TV direct via the Existing HDMI cable and the problem continued. I then switched to a new input on the TV and used a new HDMI cable that passed Bluray 1080P without problem only to find the problem continued.
HR24 has the latest update and the XBR firmware is current.

Happens on all resolutions and resolution is currently locked on 1080i.

Any Ideas????

Oh and Brent is on East coast time and old so probably in bed before California beer thirty!
Sorry Brent! (Thats what you get for not answering your phone) ;)

Sorry, I missed this one.
Did you try a DAD, since it does not appear to be resolution related it is most likely EDID.

And I dont eat at Morrisons (we dont have one in Daytona).

LOL!!! It was the oldest crowd restaurant I could think of.

Whitevan,

Did you have to switch to component?

This is all interesting and 100% HDCP issue in my opinion.

Keep in mind we might have 10 seconds of clearly playing movie before 1/2 second black screen flash or we might have 10 or 15 minutes between happenings.

The TV authenticates every time.

This is a strange hiccup in the constant handshake process that goes like this.
