No stop button on 360.

I have just migrated to the 360 from V6. When I had finished watching a programme I had recorded I saw there was no stop button on the remote. How do I stop a programme and, say, return to it the next day at the same point I left it. I understand the 360 is more a streaming service than a recording one but some channels do not have a catch up service, and recording also means I can ff through the adverts.
