Audio and Video severely out of sync

[Falcon182]

Hi, a background:

 

I have a self-built P4 3.2 HT, 1gb ram, 160gb HD, 128mb GeForce 6600GT pciE, Lite-On 8x DVD burner.

 

I created a video using Adobe Premier Pro 1.5 that is about 30 minutes in length. I exported the video to a .avi file.

 

When I create a DvD using Roxio EMC 9 MyDVD, both as an express with no menu's and a regular with menus, after a few minutes of the audio and video become out of sync, until near the end of the video when the sync is 10-15 seconds off. This is obviously unacceptable.

 

I'm not totally ignorant of video or audio compression, but this progam has stumped me. I tried creating a video using the Dolby AC3 compression at 448 (or whatever the highest is) compression. I also tryed creating a video using the MPEG compression at 384 (second from the highest) compression. Both had the same problem.

 

I'm hoping there is something simple to fix this, and that I didn't just waste $80 buying this program.

 

PLEASE HELP!!

 

PS: I have seen other threads where breaking the video into smaller segments was suggested. This is not an ideal solution, please give further advice if possible.
