Well here is all the info you need to really get a good backup copy of your DVD’s. First get the program call MacTheRipper, once you have that it will allow you to do a disk copy of your DVD. After the disk copy has completed you will be left with a folder that you created in there will be all of the DVD. Next you need to get a program such as DVD2oneX and from that program you can select the folder that you just created and it will reencode it all to fit on a DVD-R. Last but not least once DVD2oneX has done its thing you will have two folders, a AUDIO_TS and a VIDEO_TS, fire up a copy of Toast and create a DVD Video… Just drag those direcories to Toast and wait for it to burn.
Movies on a mac… I guess there is a known issue with Macs and Divx, It doesn’t play sound for the most part. Here is the fix that I found. If you are going to use Quicktime, install Divx 5, and THEN install the 3ivX codec for quicktime. Do it in that order and Divx 5 will handle the video, and 3ivX will handle the sound aspect of things.
