MovieFactory 1 - No sound afetre encoding

[Sugar]

I am working on a NTSC DVD film from DV PAL material.
I have edited my footage with Premiere 6.5. I then export the resulting movie into a Microsoft DV PAL AVI compliant file. I have done that for 10 separate films.
I then encode the .avi files with MovieFactory 1 in NTSC high quality format. This is the only encoding software, which provides me good results to convert a PAL avi file into a NTSC MPEG-2 File.

Out of the 10 films, 8 play fine. However, 2 of them do not have audio. I have used the same procedure through the process and the same template with Premiere. The 2 films are the longest with each more than 10 minutes of footage. When I look in the info box when importing the avi file in MovieFactory, it says that the data rate is 0!

I edited 1 of the 2 files to cut it to 6 seconds and did the conversion: this time, there was audio.

I spent a good part of the night trying to figure out a solution. But no luck so far.
Anybody help !

Not to worry. The files capture with Premiere are avi Type 2. Movie Factory is designed to support Type 1.
This actually takes place at capturing.

Sooooo, if you want to compress with MovieFactory, make sure your avi file is type 1, which probably means you need to capture with 1 of Ulead software or other type 1 compatible capture card /software.

You can check your file type when you press the info button in MF when trying to open an existing file.
