4k PVR not recording as per schedule

Hello, 

I have been with Videotron for only a few months now and i am getting a little frustrated with the PVR. There are shows programmed to record daily/weekly and the PVR seems to have a mind of its own. For example, a show prorammed to record daily at 2pm from Monday to Friday will record only 4 out of the 5 days.  Another example is a show programmed to record "Every Monday at 9pm" on a specific channel will record EVERY time it airs on that channel.  Before anyone asks me if i programmed them properly, yes i did, i double checked before posting this.  But honestly, i am more concerned about missed recordings that too many recordings.  These issues have been going on for months now and it happens with different shows, not always the same one. I'm not sure why this is happening but coming from Bell where this was NEVER an issue makes it a little more frustrating and it is making me doubt my decision to switch to Videotron.  Hopefully someone here can help me.
