What to do will all those iPhone videos? Seems no one can answer this?

Bring the movies into iMovie and title them. Then send them to iDVD. You need to use iDVD to create a disk that your DVD player will understand.

There are tutorials for both apps here

Each app has extensive help and there is a forum for each app also.

Sorry but this doesn't make sense:

I read somewhere if I don't want to edit them I can just use iMovie? Is that correct.

Yes you can use iMovie to not edit them? You can also not edit them with Word or TextEdit or Photoshop 😉

Adding titles is editing.

dies the format need to be changed for a DVD

Yes. DVD is a quite specific format and heavily compressed. For more on these apps you will do better posting on the relevant forums for them.

First, you will have to import your movies into iPhoto (or to disk somewhere).
Open iDVD, choose Magic DVD, then drag the movies into the slots available.
You can also add photos if you want.
If you want to give names to your clips, click new Project and go to the Chapters view and name each clip in iDVD.

If you want Titles embedded into the clip that appear on screen, you will have to use iMovie. Embedding "titles" into a movie is editing and must be done in iMovie. iDVD is not a video editor, it is a DVD authoring program.

If you want to see Nov 09 at the beginning, then you must edit the video. You can't just stick a title onto the screen. It doesn't work that way.
You can set up the DVD so that it's menu screen shows Nov 09, but if you want the "Movie" to show "Nov 09" as it starts playing, you must edit the video. iDVD is not a video editor.
