I don't know if this is a DirecTV or a Panasonic 65VT50 problem, but here's the issue... I have a DirecTV HR24 connected to this 65VT50 TV. Whenever I watch one of the 3D channels (101-107), I can do so without any problems. However, when I pull up the channel guide, all the 3D channels are grayed (faded) out, but again, I can still watch them. Consequently, when I try to record a 3D program live, I'm unable to do so. I get the message that says, "This receiver is not authorized to record this program." When I try to record a future showing of something on one of the 3D channels (101-107), I get a similar message telling me that because the "...receiver is not authorized to record that program...program may not record; choose cancel or record anyway." It used to be that for some odd reason, I'd have to have my HR24 tuned onto one of those 3D channels for 10 to 20 minutes or so before the channels "lit up" in the guide and became recordable. However, they've remained grayed out for the last several hours. Resetting the receiver didn't help this time, either. I've checked the Panny's settings, even changing 3D detect from "Auto 1" to "Auto 2" (whatever the difference is), but that didn't help. FWIW, I did notice that this problem seems to have become really prevalent after I changed my A/V to 65VT50 HDMI connection from HDMI-1 on the Panny to HDMI-2 (ARC). DirecTV doesn't really know why this is happening, so I figured I'd check and see if anyone else has experienced this and if someone might think it's a DirecTV problem or a TV problem.
