Burn .mp4 to iDVD1. Make sure your .mp4 file is in your "Movies" folder in your home folder.

2. LaunchiDVD.

3. As you are trying to squeeze two hours onto a single layer, I suggest going to preferences and selecting "best quality" for the encoder settings. This will increase encoding time.

4. Create a new project.

5. Press the "customize" button.

6. Select a low-motion theme such as "Transparent Black" (found in 4.0 themes, which is selected from thedrop-downmenu).

7. Press the "Map" button, which is to the left of the play button.

8. Press the "media" tab (on the left, in the customize drawer), and then choose "Movies" from thedrop-downmenu. In the browser, find your .mp4 and drag it over the "Full Frame 1" picture in the tree structure. A new extension to the tree should be created under/next to "Full Frame 1".

9. Press the "return" button (in the GUI, not the keyboard).

10. Edit (by clicking once to select, waiting, then again to highlight; e.g. like editing a file name in the Finder, not a quick "double click") the titles in the theme. I suggest deleting "Transparent Black" altogether, and renaming whatever appears underneath to "play"

11. Now, if you press the preview button, clicking on "play" (or whatever you chose) should play your .mp4.

12. Press the preview button again to end the preview.

13. Now, burn the movie.

IfiDVDstill says the movie is too long, do you have Toast?1.) Download and installFFmpegX. Make sure you read all the information at versiontracker, you have to install other components too in order for ffmpegX to work.

2.) Launch ffmpegX, click "open...", and choose your .mp4 file.

3.) In the "to" box under "target format" on the right, choose "DVD mpeg2enc"

4.) Click on the "video" tab, choose "1" CD of "DVD 4GB" in thedrop-downmenus on the left, and click the "rate" button. This will automatically choose an appropriate bit-rate. Make sure the dimensions and frame rate on the right are correct.

5.) Click audio and choose .ac3 from thedrop-down. Select the bitrate etc. that you want.

6.) Click on "options" tab, and on the right, choose profile as "DVD" and click the "author as" tick box (at the bottom) and choose "DVD (VIDEO_TS)"

7.) Click back to summary, press "save as..." and choose a destination location and file name.

8.) Press encode. When it is done, you should find a new folder, whose name ends .DVD, in the destination that you chose. That folder should contain an "AUDIO_TS" folder and a "VIDEO_TS" folder.

9.) Launch Toast.

10.) Select the Video tab, and in the drawer on the left, choose "DVD-video from VIDEO_TS", then drag and drop the VIDEO_TS folder created in step 8.) above to themain window.

11.) Burn disc.If your MP4 files play correctly in QuickTime Player you can just drag it into the iDVD and it can burn MP4 files to DVD on your Mac (Lion, Snow Leopard included). However, some MP4 files are encoded with codecs that iDVD can't recognize.In that case use mpegStreamclip to convert the file to DV.Once you have the project as you want it save it as a disk image via theFile 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.Thenburn to diskwith 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.Or use miDvd software...
