Why does audio run faster than video after burning my iMovie project in iDVD?

Question

I created a project in iMovie HD and shared it to iDVD 6. When I played the finished disc, I noticed that the audio ran much faster than the video. I rechecked my movie and audio clips in iMovie to make sure they were matched correctly, and I saw no problem there. I burned the disc again through iDVD and got the same problem when I played it in a DVD player.
I have never had this problem before and I've been working on dvd projects all week. I think the only difference with this movie project is that I had movie clip audio and background audio playing at the same time at some parts of the movie, but I don't know if that's the issue.
Any suggestions?

Hi
And just to add to OT-s brilliant suggestions - really - Do a Save as a DiskImage ! IMPORTANT !
• When free space goes down on the Start-Up hard disk to 5Gb or less - strange things occurs - Yes even audio out of sync - to not working DVD at all.
I secure a minimum of 25Gb free space when using SD-video to iDVD - if HD material I would guess 4-5 times more as it has to be re-calculated into SD and this needs space.
DVD - is as standard SD-Video (as old time CRT-TVs) - even if You use DVD-Studio Pro or iDVD or Roxio Toast™ - That's what it is and using HD material doesn't improve a bit (may be even give a lesser result)
