I had a hand on Daniusoft DVD ripping software just last month. You can refer to my blog in December 2007. At that time I found Daniusoft an intriguing software to rip DVD for AppleTV. I was wrong. I found lot of problem on many DVD tilte to appear with sound out of sync to the picture. I had contact thier support. An agent named Alex had responded. I gave them as much details as possible. Now their support turn to silence. I haven't heard from them again since. My problem is still not solved.
Luckily, I just came across a new free software, called HandBrake. It a good DVD ripping software with output to many device format ranging from iPod to AppleTV. The output picture and sound quality are excellent. I get full display on my wide 16:9 Plasma screen. However, the interface is not at all attractive. It requires some understanding about the Display ratio. I am impressed with the solution. esspecially its free. Thanks to the development team. They really made the world a bit nicer to live on.
