@KM1212 : You cannot do what is called "manual recording" using the latest firmware. Yes, this is/was available on SARA firmware for the older boxes.
You will need to set up a single recording each week if the name changes, or perhaps figure out a workaround. For example, if the same programme is on every week before, or after the movie of interest, you can set a series recording for that programme and extend the recording by 3 hours, either before, or after that recording depending.
