Welcome to the Community, I'm so sorry for the problems you're experiencing with your TV service recently.
I've located your account to run some tests on the set top box from our end and we're not detecting any errors at the moment. Are you noticing this issue occur at certain times of the day or is it something that is happening at all times?
Are you noticing any other parts of the menu operating slowly or is it just the recordings?
Sorry for all the questions! We want to get to the bottom of this as soon as possible.
