1. The first step in watching videos that you already own is to get them on your computer. If it’s a DVD, just pop it into your computers DVD-rom drive. Next you will need to get a DVD ripper this will allow you to put the dvd movie into your computer’s hard drive. This will take sometime depending on what dvd ripper you have. (If you already have the videos that you want to watch on your iphone on your computer’s hard drive go to Step 2)
2. To watch the videos on your iphone you will need to convert the videos you already have to the iphone format. For this you will need an iphone video converter or any other program that converts video files to .mp4 (H.264 encoding) because this the only format of video that the iphone/ipod plays. This will also take a while depending on how big your video file is and how good your iphone/ipod video converter is.
Now before you continue on putting the video files onto your iphone make sure all of them are in the proper iphone format. You do not need to worry about this if you used a video converter that converts videos to iphone format.
3. After you’ve ripped and converted all the videos you want all that is left to do is to actually put it on your iphone/ipod. This is by far the easiest step and takes the least time because this can be done right from itunes. All you need to do connect your iphone to the computer. Then open up itunes scan the video files into the itunes library and then put the videos files right from itunes to your iphone or ipod video.
