These movies are in REALPLAYER *.rm format and you do not have to wait for complete downloading before you get to view them. They are in STREAMING mode and will start to play within a few seconds of the commencement of downloading, if you have REALPLAYER installed.
If the net is very busy and the movie suffers minor interruptions while streaming down, then simply click on the slider and move it back a little. You will see some of the movie that you have already seen, but the streaming will have continued while you were doing this and you will now get a continuously flowing movie, hopefully right to the end.

Note: If you wish to replay a movie you will need to click on the slider just before it reaches the end, then move it back to the start. There won't be any interruptions this time, BTW.

If you are used to waiting around for things to happen while you look around the net, you will be pleasantly surprised by the speed of delivery of these streamed movies.
