Whenever you rent a movie from the iTunes store, you have 30 days to watch it. After that period, the video becomes unavailable. Also, when you buy a film from the iTunes store, you cannot transfer it to a USB storage device or share it with other people. A solution for these two issues comes from Tune4mac iTunes Video Converter Platinum.
This utility helps you get rid of the DRM protection from any video you purchased or rented from the iTunes store and convert it to dozens of media formats. The application lets you import as many clips as you like from your iTunes library, choose between multiple output formats, and even trim the videos if necessary.
Tune4mac iTunes Video Converter Platinum can easily be handled by average computer users as it features simple-to-configure output settings. Another advantage is that this utility preserves the quality and subtitles of the original videos.
In my testing, the app took a while to convert the input video (the clip had 1 minute, the program took 5 minutes to convert it). So, you might need to wait several minutes to convert lengthy movies.
However, this program preserves the quality of the films, retains all subtitles, and doesn't slow down your Mac while converting the DRM-protected files.
