The email alerts warn you that one of your recorder failed to schedule one or more of shows. It is not a warning that a show actually failed to record. Though they will fail to record if you don't resolve the cause of the error and reschedule the show(s).
IceTV always schedules series recordings 5 days ahead therefore if the recorder fails to set a schedule you will get the error 5 days before the show is due to record (with plenty of time to resolve the problem).
Some PVRs often use the Invalid Service error when they don't have a more suitable error message to use. This error can often mean the guide was blank for that timeslot or the show did not match. This can happen on PVRs that do not correctly update the guide when shows change (even by just 5 minutes).
It looks like the guide on your PVR may not have had those shows in it when they were trying to be scheduled. They were both a full 120 hours ahead when they failed to be set by the PVR.
Strangely, that NITV error with no show name appears to be Volumz but it is at midnight and not 4:00am.
I have rescheduled the 2 shows had an error in you're My Week, so they should hopefully get set okay now.
