Do iTunes movie rentals work on video iPods yet?
Not all iTunes video can be transferred to iPod, please make sure your video is compatible with iPod. If the video resolution or video bitrate beyond iPod limitation, even though they are mp4 video, you can’t upload them to iPod. For example, some iTunes purchased movie are High definition movie, the resolution it too high to play on iPod, you can’t sync it to your iPod. For more information about iPod compatible video, you can visit apple official website. http://www.apple.com/ipodtouch/specs.htm… Or you may take a look at this step by step direction, it’s about how to convert and put video to iPod, it works pretty well for me. http://www.dvdintoipod.com/rip-dvd-movie… Hope it helps.
