Q: iDVD shows shaky "Ticker "  Titles  once the Movie has been burned but the Titles were not shaky when making the video in iMovie . Any thoughts please .

What are you viewing the final DVD on? It sounds like it could be an interlacing issue.

In DVD player on OS X there is an option to change the deinterlacing, see if that has any effect. VLC has even more options for deinterlacing.

TV's may not have settings to alter this, it really depends on the player & monitor.

Was your workflow similar to this recommended workflow?

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 not try using it and test the disk in both DVD players.

The general practice is to make your source match the expected destination output.

If the end user is likely to be on a computer you would deinterlace the movie before making the DVD.

If the destination is aware of fields (TV's, DVD players etc) you would leave the source interlaced. New monitors are progressive, but can still deinterlace.

Deinterlacing an interlaced source will 'soften' the appearance but it can resolve the shakiness that happens when motion is happening across 2 fields.

Another option is to adjust the scroll rate until it is less noticeable, but that is difficult without an interlaced monitor connected to your edit suite.
