I've noticed this a few times recently, but only investigated fully earlier today.
I have a HR23 connected to a Sony 40" HDTV via HDMI cables. The Sony is 1.5 years old. I have no problem watching HBO on the Sony.
Before I had the HR23, there was an R10 in its place, and the coax output from the R10 was sent into the house wiring to 2 other SD TV's in other locations in the house. When the HR23 came, I got an RF modulator to do this. Composite on the HR23 into the modulator. When the HD UI came out, I got a Component to Composite converter, and so the Component cables go to the converter, composite to the modulator, and then the coax to the other rooms in the house.
So, I noticed the "can't watch this channel with HDMI cables, switch to component cables" on one of the remote TV's - a pretty old back-projection Sony. I ran to the other remote TV (an 8-year old Panasonic) - it was showing the HBO program from the HR23. I checked the Sony HDTV connected with HDMI cables, and it was also showing the program fine. Back at the first TV, the "HDMI" error was still showing.
I went to a local channel, and picture returned on the old Sony. I then went into the recorded programs list, found a HBO program, and started playing it. The UI showed fine all the way until I hit the "play" button, then the screen went blank and the "HDMI" error came up. The recorded program was showing fine on the HD Sony and the Panasonic.
So, can anyone explain this? I thought the component-composite converter and the modulator both just blindly showed whatever was coming out the receiver - which in my case should be exactly what I see on the HD Sony (as it handles the HBO programs via HDMI OK). I can't believe there's any communication to the HR23 from the remote TV's - via 60 foot of coax and a modulator and converter. I also can't believe therefore that the program would show fine on one old TV, but not the other. Surely I should at least see the same on both old TVs? Of course, the final irony is the message tells me to use Component cables - which is what I'm using already to feed the modulator!
Its not the end of the world, as the old Sony has a R10 on it also, where HBO works fine. (The Panasonic relies solely on the coax feed from the HR23) I'm just stumped by what is going on here.
