I have just bought an Acer Iconia Tab tabelet for watching films on, as I consider my GS3 too small for action-filled movies. I am new to google Play Movies and wa wondering if a rented film is downloaded to your device and simply won't play after the 48 hour play period, or whether the film is streamed. This is important as I will be travelling to Switzerland tomorrow and I want to watch a film I rented on a long train journey, but I won't be able to use the internet ot stream it while on the go.

So can I watch my film at any point during the 30 activatino period or do I have to be connected to the internet at all times to watch it?
