Sorry for such a noob question, but how would I go about doing that?
Would I need to convert the movie after d/ling (not sure what format Amazon uses)?
Not quite clear on how to transfer to tablet or where I would put the file.
Thanks
How to Convert Downloaded Amazon Video to ASUS Transformer Prime --- instructions on how to download a movie from Amazon to your pc and then convert it to a format that can be played on Android tablets (the conversion program is free.)
Transferring from your computer to tablet is fairly easy and can be done two ways:
1. via wifi if they are both on the same network (may take some time to set that up)
or, easier:
2. connect your tablet to your computer via the cable. this will let your computer "use" the tablet like an external memory stick. drag and drop converted movie from computer to tablet.
As to where to put the file -- make a folder in your tablet (maybe call it 'Movies' or something

)... then (using the explorer on your computer), drag the converted movie from computer to the new folder you created.
I use MX Player (free in Play Store) to watch movies, videos, etc -- once you open the app, set it to retrieve 'Movie's folder... if you always drop your stuff to this folder, MX Player will always find them.
If you have DVDs you want to convert -- I wholeheartedly recommend look at a program for your computer called DVD_Catalyst... it's about $10... it's fast, robust, and converts movie to about a bazillion different formats if needed.
