We have been advising customers to reboot the X1 dvr by holding the power button on the front until the dvr powers down and then pressing the power button again. It seems to clear the lagging issue.
We just got them in our plant two weeks ago. Only in house techs have access to them here. Of your installation is done by a contractor, you may be out of luck.
It's been working pretty well on my PS4. This is my first baseball season out NY Yankees territory, and it's been a godsend for me thus far.
