I upgraded my two TiVo Premieres to TiVo Bolts, and also added two TiVo Minis. My Premieres worked great together, including being able to see each other on the network and watch shows across the network. But since I upgraded, I've been having issues. The Bolts can play/record shows, and play shows off of the internet (Netflix, HBO Go, etc.). They can see each other on the network (i.e., they show up in each other's device list), but neither can access the other's recorded shows. My two boxes are called "Master Bedroom" and "Living Room". If I'm on Master Bedroom and I go to My Shows => Devices and click on Living Room, I get this error: I've tried all of the troubleshooting tips there, to no avail. The only non-standard thing about my network configuration is that I have a LinkSYS Velop mesh network, and I'm using NetGear Powerline adapters to extend my network over the electrical wiring to the rooms where my Bolts live - But it's the same configuration that the Premieres used successfully. Further, the Minis can't see the Bolts. If I do a network test, the port test fails, and it tells me I need to open port 37. I suspect whatever is keeping the Minis from seeing the Bolts is related to the reason the Bolts can't see each other. It seems that it's saying port 37 is being blocked within my internal network, but all the documentation I've found suggests that port 37 needs to be open to the internet. Either way, I don't have anything specifically blocking that port. What's even more maddening is that I brought one of the Minis into my home office and worked on it off and on for weeks. I was finally able to get it working for a couple of days - I'm not sure exactly what I did to make it work, it just happened to be working "the next time" I turned on my TV. It seemed stable, so after a couple of days, I moved the configuration into the spare bedroom where I want it - And it stopped working again, just like before. I'm out of ideas. Any help would be greatly appreciated!
