Indeed you can and after, but you are setting 'times' to record on a channel, look on the schedule, you are not recording a program. With Sky you record the program whenever it starts until it ends, even if delayed.
As a Sky user that swapped to VM fpr a year,the VM tv interface is awful. The killer for me though is that recordings record to a set time, not the program like it does on Sky. So if a program starts late, the VM recording starts on the set time and finishes on time set.
