I was checking out the website of a rural parish in Ireland and I noticed that the main parish has many small churches in the surrounding villages. The small churches don't necessarily have a priest and the priest from the main village has to come down to the smaller ones. On the parish website it indicates that you can listen to the Mass on the radio and on the TV.
If you were in the little villages with no priest can you fulfill your obligation by watching the Mass on TV or by listening to the radio? The main village is a 20 minute bus ride from the smaller ones so it's not like it would be impossible to attend.
