Looking for an Ap similar to iDVD

For something "similar" to iDVD go to the App Store and search for "video DVD" or just "DVD". However, none of the apps can come anywhere close to the capability and versatility of iDVD but can burn video DVDs. If you can get one that can can save the project to a disk image so you can follow this workflow to help assure the best qualty video DVD:

Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image menu option. This will separate the encoding process from the burn process.

To check the encoding mount the disk image, launch DVD Player and play it. If it plays OK with DVD Player the encoding is good.

Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality. Always use top quality media: Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.

If you expect to create a lot of video DVDs you might consider creating a boot volume on your current boot drive or on an external HD with Mavericks. That way you can boot into Mavericks when you want to create a video DVD with iDVD. Also having a Mavericks boot volume will let you use iMovie 6 HD (if you have a copy of it) with iDVD. It's the best iMovie version ever offered for creating slideshows from stills and using multiple audio tracks.

If you have iDVD on an older computer you can try moving it to your new one so you can create iDVD projects and save them as disk images. Then copy the disk image to the old computer and burn it there with its optical drive.

To copy iDVD from the old to the newer Mac do the following;

1 - copy the iDVD application from the old to the newer Mac.

2 - locate a folder titled iDVD that's either in the User/Home/Library/Application Support folder or the HD/Library/Application Support folder and copy it to the same location on your newer Mac.

NOTE: In Lion, Mountain Lion, Mavericks, Yosemite and El Capitan the Home/Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and press the Return key - 10.7: Un-hide the User Library folder.

For Mavericks, Yosemite amd El Capitan go to your Home folder and use the View ➙ Show View Options menu to bring up this window:

3 - launch iDVD, go to it's Advanced preference pane and point it to the Themes folder that's inside the iDVD folder you copied over.

4 - follow this workflow to help assure the best qualty video DVD:

Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image menu option. This will separate the encoding process from the burn process.

Apple got rid of iDVD because the DVD format is on it's last days... much akin to the demise of VHS. Pretty much everything is being offered in a digital streaming format now. My entire DVD collection is in a digital streaming format now (I have a Plex Media Server setup)... haven't used a DVD player in years. Content providers have been moving towards this for a number of years, the writing is on the walls, Apple just made the switch a lot sooner than the rest of the market.
