Watch Movies on R4 Card

1.
Step 1

Convert your movie file into a DPG file. You will need a video
converter for this. There are many freeware converters, such as SUPER,
which are easy to download and use. There is also DVDFab, which is not
freeware, but has a 30-day trial and can convert whole DVDs into DPG
files.

Go into "System" and then "Movies." If a "Movies" folder is not
present, create one by right-clicking and selecting "New Folder."
Click and drop the movie into this folder, then disconnect the R4
card.

If you want to get more organized, you can even create other
folders in "Movies" such as "Comedy" or "Action."
