Kind of OT for my own curiosity, does anyone know the approximate size of a movie download? I'm a computer idiot here so be kind. I can't do it but I'm just wondering where I stand in terms of being able to do it. Thanks. :D

It depends on the quality of course. In case you need to limit the amount of bandwidth you use, they give you and option to select the quality of the stream. This is what their quality selections are:

Good quality (up to 0.3 GB per hour)
Better quality (up to 0.7 GB per hour)
Best quality (up to 1.0 GB per hour, or up to 2.3 GB per hour for HD)

This list does not include the previously mentioned "Super HD". I did a search for how much bandwidth that uses up. I didn't find anything solid, but one site claimed it is 2.7 GB per hour.
