DVD audio out of sync !!

I have a nasty sound sync issue which appears when I burn MPEG file on DVD. The same problem occurs whether I burn directly from MSP7 (SP3) or if I use DVDW2 (with latest SP installed). I have been working on this project for months and never had this problem before. MPEG file itself does not have this problem.

I have several (3) sound tracks in a project which is 42 minutes long. Only one of the tracks seems to have this problem. The sound is about 1 sec out of sync.

This has occurred at a time when I have just recently noticed two other problems, and I suspect they could be related. The other two problems are:

1) My computer's DVD reader is unable to read DVD's! I have tried it with several different software including Media Player, several Intervideo products, Interactual Player. This applies also to commercial DVDs. Media Player, for instance, shows a message "unknown DVD". I never had this problem before.

2) If I open an MPEG file (which is on my hard drive) in Media Player, I get a message saying "error downloading codec". The after some time the MPG file does start playing, and seems to be playing ok. No audio sync problem.
But I get this message on all MPEG files, even the ones created long time before this problem appeared. So I don't think the file itself is corrupt.

The MPEG file is aout 2,5 G, so plenty of room on the DVD.

I used to use (without any problems at all) the following settings creating MPEG files:
24 Bits, 720 x 576, 25 fps
Lower Field First
(DVD-PAL), 4:3
Video data rate: 8000 kbps
Audio data rate: 224 kbps
Audio format: MPEG

For burning I used setting:
Burning speed Max

After the problem occured I have tried burning at slower speeds and I have reduced the data rate to 6000. I have tried both one and two pass encoding. But to no avail.

Most of the audio editing I have done recently has been adding .waw files to a voice-over track. They seem to be in sync ok.

Have I somehow lost a codec from my computer? Could this have occurred when I deinstalled (and reinstalled) Interactual Player?
Could this be the reason for my audio sync problem? If so, how come only one sound track is affected? Should I download a media Player codec from Microsoft site? I have version 10, but the latest codec available is version 9. Does MPlayer 10 use version 9 codec? Should I try other than MPEG audio format?

I have checked al the numerous audio sync isues on this forum. But none of them seem to provide the answer for my case. Any advice would be appreciated!
Thanks!

Re-Install WS2 along with the patches to install the correct codec for mpeg2 on the system.

Audio Sync:
One of the Mpeg2 files is corrupted.
(maybe VideoRedo could repair it).

Thanks,

I solved the problem partly following your advice to reinstall. The problem was corrupt MPEG files created by MSP7. I posted a slightly more detailed description on MSP forum.
