Out of sync problem with Studio 9.3.5 after burning to DVD

[dvddemon]

I currently have an 1h and 10min movie I want to burn to a DVD. They are all AVI format, and I have 3 menus in my project. It plays perfectly in the edit mode but after I burn to a DVD during playback it gradually gets out of sync with the audio. I am burning in PCM audio and I am wondering if burning in MPG audio may help resolve the problem? I am burning at a 6000k/bits bit rate at 2X speed. It plays OOS in several DVD players and my computer. I shut all background processes off, and I have burned successfully dvd's in the past no problem

Any suggestions?

From your post it seems that you have combined several avi files. If this is true then one thought that comes to mind is whether the audio bitrate and frequency is the same for each avi clip and if you are matching the audio bitrate and frequency when authoring.

Ideally you want to have the same bitrate throughout the entire movie and you should match it when authoring.

Yes I do have about 20 avi files, these files were actually various avi and mpg files I had downloaded off the internet. I re-encoded these with Pinnacle's T-rex program to AVI DV. I dont know if this encoder changes the audio encoding or not. For now I think I will output my 20 avi files into 1 avi with studio and keep them at a constant bit rate and khz. Then I can re-import it as 1 file, re-create my menus and hopefully this may solve my OOS problem.

wwjd, thanks for your advise this has appeared to work. I did not know what frequency or bit rate each file had but what I did was outputted my entire movie into 1 AVI file, this would keep the bit rates and frequencies at the same level. Then I imported the avi file back into studio, created my menus again and burned. Now its perfectly in sync! Thanks again
