First, beware installation of so-called "DivX codec packs."

http://www.microsoft.com/windows/windowsmedia/software/v7/v7faq.aspx?section=CODECS&qu...S1#NAME_CODECS

According to Microsoft:

"Nimo and Tsunami codec packs are untested compilations of various codecs and filters commonly used on the Internet."

"Incompatibilities are known to exist with some of the components in the packs."

"The incompatibilities can cause serious playback issues in Windows Media Player and other multimedia programs, lead to system corruption, and make it difficult for Microsoft Support to diagnose and troubleshoot playback issues."

I mention this only because it's possible you may have installed one of these and it could negatively impact the Ulead programs that you have installed.

Second, the issue you describe concerning audio/video synchronization.

I never have experienced this - even with DVDs lasting longer than one hour - when using Ulead DVD MovieFactory 2.

On the other hand, my input is not "AVI/DivX" as you described it.

I always input DVD compliant MPEG-2 files.

For example, the high quality MPEG-2 recorded by my Panasonic VDR-M30 DVD disc camcorder has the following precise attributes:

NTSC drop frame (29.97 fps)
MPEG files
24 Bits, 704 x 480, 29.97 fps
Field Order B
(DVD-NTSC), 4 : 3
Video data rate: Variable (Max. 8800 kbps)
Audio data rate: 256 kbps
MPEG audio layer 2, 48 KHz, Stereo

This information provides me the information I need to properly adjust my Ulead DVD MovieFactory 2 project settings.

To avoid unnecessary re-encoding, I adjust the project settings to be *identical* in every way to the SOURCE.

If I were in your situation - and somebody had just handed me "AVI/DivX" source material, I would first attempt to re-encode it to a DVD compliant format using a video editor such as Ulead VideoStudio 7 or Ulead MediaStudio Pro.

Then I would inspect the encoded file for any audio abnormalities.

If there were no problems, I would then import the file into my authoring application for recording to disc.

I suspect the installation of the software on your computer is having a tough time doing all of the menu creation chores *plus* the encoding of non-compliant source material to a DVD compliant format.

Thanks for the info Jerry. I have both VS and media pro. Which would be quicker if any at creating an out MPEG file.

Should i consider removing my DIVX codecs, where could i get genuine codecs?

Either Ulead VideoStudio...

...or Ulead MediaStudio Pro...

...will handle the file creation.

You can decide based on your individual comfort level.

Personally, I do not install DivX codec packs and I would not only uninstall any such packs, I would reformat drive c: (system) and perform a clean installation of Microsoft Windows - if it were me.

It's your computer and you can and should decide for yourself.

As for the official DivX codec, I personally have no need for it.

You might look at this Web site...

...if you're looking for an "official" DivX codec.

Of course, these are all decisions that are up to each individual.
