Welcome to the myDVDEdit site

My hope is that myDVDEdit will be to DVD's what ResEdit is to programs on the Mac, a tool which allows you to understand and even to modify the content of a DVD, at the deepest level.
The format of a DVD is very complex. I have tried to make it as accessible as possible and have therefore left aside explaining some bits of information, which, although they are important in enabling the DVD to be read by the DVD player, are of no importance to anyone who simply wishes to understand the DVDs structure.

myDVDEdit cannot read protected DVD videos, and it will never be able to do so. It has not been created to violate copyrights. It was created to enable you to understand how DVDs work, to help you create new DVDs step by step, and make DVD changes which cannot be made with the traditional authoring tools.

 

WARNING: The use of myDVDEdit is done at your own risk. I cannot take any responsibility for any damage you inflict to your DVDs by using it. Always work on a copy of your VIDEO_TS folder and save your work regularly.

Because I have never had the official documentation on the format of DVDs, I have written this program solely from data collected on the Internet, from free sources, and from discussions on forums.

myDVDEdit has been entirely written in Cocoa. The software is in both French and English.

For the moment, myDVDEdit is a DonationWare. It is perfecty functional, and will never ask you to enter any code or license information. You can however support future development by making a donation.

Please do not hesitate to send me your comments, suggestions, or to report any problems with myDVDEdit on the relevant forum. You can also ask any questions there concerning myDVDEdit or the DVD format.

No questions will be answered by email.
