Not a solution! A weak workaround at best but I tried it - no improvement. I subscribe to most, but not all, the channels. This is clearly a VERIZON mess (or plural since it slows the guide, the channels, DVR, and everything else) and they need to fix THEIR end.
A solution fixes the problem, anything else is an excuse.

The solution presented was accurate for the version of software on the boxes three years ago. There have been many upgrades since. The September 2020 update caused slowness issues with older models of boxes. I suggest you start a new thread to get help from other users, or read some of the recent threads about performance issues.
As this thread is now over two years old, it will be locked in order to keep discussions current. If you have the same or a similar question/issue we invite you to start a new thread on the topic.
