Audio dropout in Quicktime export

[question1]

I am trying to create a DVD out of a long (1+ hour) iMovie project that I have. When I export, choosing "For iDVD," the Quicktime file that is created has smooth video but the audio drops out and gets off time. Very frustrating. I have a 933 G4 that has 256 RAM, could it be a memory problem? Any ideas around the possible cause or possible solutions would be GREATLY appreciated. Thanks.

GET MORE RAM!!!!

If you are doing this under OS X (which I will assume since you didn't mention which OS you are running), 256 is nothing. Get at least another 512 into that puppy and check back with us. Hell, get a pair, they're small :D... pump it up to at least 768MB or 1GB+ of memory.

You will be glad that you did.
