newbie questions

Ok, my son is making a video of our local elementary school talent show. 
It is 2 hours 11 min long, we edited in iMovie 2 and exported to quicktime. 

then found out it is too long for iDVD to make a DVD from. 

also the audio lost sync at about 3/4 the way thru the movie.

any suggestions or step by step instructions on the web to reccommend

iMovie
iDVD
os 9.22 or 10.23
mac 933 Quicksilver
120 GB drive just for data
13GB for system
60 for all else
1.25 GB RAM

Thanks,
