I have tried converting a few dvds to mp4 using clonedvd mobile 126.96.36.199. The problem I have is that the audio gets out of sync pretty bad. I tried 3 films, The Incredibles, Without a Paddle & Willy Wonka. All 3 did the same thing.
I have Nero Recode and I used recode digital to make mp4s and they are all fine. They take about an hour per film however and Clonedvd mobile only takes 30-35 minutes. I wanted to use clonedvd mobile as it is faster but I cannot figure out the sync problem with it.
