I have a TiVo Roamio, purchased in 2015, with Comcast Xfinity TV / Cablecard.
A few years ago, seemingly as a result of a thunderstorm, the HDMI port on the TiVo box failed. I switched from HDMI to Composite hookup to the TV, and everything worked fine.
In Dec 2019, we replaced our TV with a TCL 5-series Roku TV. The newer TV does not have a composite hookup. I purchased a cheap composite-to-HDMI adapter (Amazon.com), which worked great for several years.
A couple of weeks ago, I suddenly got an error message on the TV: "HDMI connection not permitted. Press SELECT for more information." The "more information" is: "HDMI not permitted. The copyright holder of this video does not allow it to be viewed on an unsecured device connected with an HDMI cable. If you were trying to wathc this video using an HDMI cable connected to a TV, that TV is not correctly supporting HDCP (HD copy protection) and you will need to switch to using a different cable." I can see the picture on the screen, but it's obscured by the error message bouncing around.
The problem doesn't seem to be the TV, given how relatively new it is (I also tried the other two HDMI ports on the TV, but it made no difference). Restarting the TiVo had no effect. I swapped out the HDMI cable; no effect. I purchased a new composite-to-HDMI adapter; again, no help.
I have a TiVo Mini hooked up as well, and have had no problems with it at all. I can watch recorded shows on the second TV without an HDCP error, but can't watch the same shows on the main TV.
Any thoughts? The only other step I've considered is getting an HDCP 2.2 to 1.4 converter, thinking that maybe the composite adapter is only transmitting a 1.4 signal and I need to convert it to a 2.2 signal to get the TV to detect it properly.
