Cannot pause or rewind live TV again

UPDATE - rebooted cable box. Worked for awhile. Now when resuming a paused show it will start playing a little, then it will jump to live TV skipping the paused part of the show.

Tried "rewinding back" the show, but it only played a few seconds and then skipped to live again.

Remote batteries were recently changed, and still show 100%.  Seems ridiculous to have to reboot again less than 24 hours after the last reboot.

Having a similar issue to what I've seen others experience where the "blue line" dissappears after a non-specific period of viewing.

Can no longer pause live shows to step away from TV for break. Sometimes can pause, but then when we resume the program "jumps" to the "live" position, and we miss everything that has occurred. 

Have tried actions recommended in this (and other threads), including x1 box reboot, but problem returns. We're paying almost $300/month and not getting functionality we've had for years. What gives?
