4k PVR Issue (recordings cut short)

This is a very annoying. My 4K keeps doing this as well. I called a few weeks ago and a technician seemed to fix the issue but it’s starting to happen again. So annoying when we go to watch a recorded program only to find out it cut half way through or at 10 minutes before the end. I’m tired of calling and wasting my time on the phone with videotron. There have been so many issues from my bill never being what it’s supposed to be to very slow internet and now the tv service is going. I’m thinking of making the switch to bell as well as I feel my time is being wasted on the phone trying to fix issues that shouldn’t be issues!!!
