Hello Everyone!
Well my Iphone is SYNC to my macbook. I will be going on a trip and I am currently doing a workout program (P90x). I wanted to add 3 videos onto my Iphone so I can carry it to the Gym.
I used a program named IMToo DVD Ripper, which helped me change the DVDs' to MP4's. I did this using my PC because I did not want my MacBook to get super hot again. ( It did this last time I was trying to convert videos)
Now, how can I add these Video Files, which are on my PC, to my Iphone without losing the Data that is already within it?
Thank You for your suggestions!
