Good dvd creator app for iMac

Question

I'm looking for a solid app to create DVD's that will contain more that one movie with a menu of my choosing with background music. Most seem to fail with adding the background music on the burned DVD. Any help is welcomed

The very best video DVD authoring application, IMO, is iDVD. Granted it's been discontinued but there really is no substitute that can produce as professional looking, multi menu product as iDVD. iDVD offers nearly 90 different themes to choose from. As of now iDVD is compatible with Yosemite.
If iDVD was not preinstalled on your Mac you'll have to obtain it by purchasing a copy of the iLife 09 disk from a 3rd party retailier like Amazon.com: ilife 09: Softwareor eBay.com.  Why, because iDVD (and iWeb) was discontinued by Apple over a year ago.
Why iLife 09 instead of 11?
If you have to purchase an iLife disc in order to obtain the iDVD application remember that the iLife 11 disc only provides  themes from iDVD 5-7.  The Software Update no longer installs the earlier themes when starting from the iLIfe 11 disk nor do any of the iDVD 7 updaters available from the Apple Downloads website contain them.
Currently the only sure fire way to get all themes is to start with the iLife 09 disc:
This shows the iDVD contents in the iLife 09 disc via Pacifist:
You then can upgrade from iDVD 7.0.3 to iDVD 7.1.2 via the updaters at the Apple Downloads webpage.
Export the slideshow out of iPhoto as a QT movie file via the Export button in the lower toolbar.  Select Size = Medium or Large.
Open iDVD, select a theme and drag the exported QT movie file into the open iDVD window being careful to avoid any drop zones.
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.
I've not been able to test any of the other apps as I haven't found any that have a demo version. 
When the time comes when iDVD is no longer compatible with Yosemite or its successor I have an external HD that has Mavericks on it which I'll boot into to use.
