Ulead's DVD MovieFactory 2 will give you a message stating that AC-3 isn't supported, but if you ignore the message and continue - the program will accept the file and burn it to disc without re-encoding if you check the DO NOT CONVERT COMPLIANT FILES box.

Even Ulead's non-AC-3 video editing and DVD authoring applications
will not re-encode AC-3 MPEG source files if the user understands the
limitations.

Consider...

1. DVD MovieFactory 2...

...and...

2. Ulead VideoStudio 7...

http://www.ulead.com/vs/runme.htm

While these two Ulead applications do not have the native ability to
CONVERT NON AC-3 audio MPEG sources into MPEGs with AC-3 audio...

...they do *NOT* re-encode unedited, AC-3 SOURCE MPEGs when burning to disc IF ONE FOLLOWS THE CORRECT STEPS.

In my numerous tests, I succeeded in burning an AC-3 DVD-RW using
Ulead VideoStudio 7's disc authoring module (and the test results were
identical to those I encountered using Ulead DVD MovieFactory 2)

1. I opened ULEAD VideoStudio 7.0;

2. I clicked SHARE > CREATE DISC;

3. I clicked the button in the far lower left hand corner of the disc
authoring module;

4. I clicked DISC TEMPLATE MANAGER;

These were the settings I chose:

MPEG files
24 Bits, 720 x 480, 29.97 fps
Field Order A
(DVD-NTSC), 4:3
Video data rate: 8000 kbps
LPCM Audio, 48 KHz, Stereo

5. I then clicked CLOSE;

6. I then clicked the SECOND button in the lower left hand corner of
the disc authoring module;

7. I checked to make certain the PROJECT SETTINGS were as follows:

MPEG files
24 Bits, 720 x 480, 29.97 fps
Field Order A
(DVD-NTSC), 4:3
Video data rate: 8000 kbps
LPCM Audio, 48 KHz, Stereo

8. I then UNCHECKED and then RECHECKED the DO NOT CONVERT COMPLIANT
MPEG FILES box;

9. I then clicked the ADD VIDEO button and imported an MPEG-2 file
with AC-3 audio;

10. I right mouse clicked on the file and then clicked MEDIA CLIP
PROPERTIES to observe the following properties of this file:

FILE FORMAT: NTSC DVD
FILE SIZE: 27,542 KB
DURATION: 26.94 seconds
VIDEO TYPE: MPEG-2 Video, Field A
TOTAL FRAMES: 806 Frames
ATTRIBUTES: 24 Bits, 720 x 480
FRAME RATE: 29.97
DATA RATE: 8000KBPS
AUDIO TYPE: DOLBY DIGITAL AUDIO
TOTAL SAMPLES: 1,290,891 Samples
ATTRIBUTES: 48,000hz
BIT RATE: 256kbps

11. I clicked the NEXT button and configured the menu;

12. I clicked the NEXT button and I watched the preview; the sound was
not audible (normal with AC-3);

13. I clicked the NEXT button and checked the RECORD TO DISC box;

14. I then clicked the OUTPUT icon and the burning process initiated
and completed;

15. To test that the AC-3 audio had been passed through to the disc
successfully - IN SPITE OF THE LACK OF OFFICIAL AC-3 SUPPORT - I then
selected Ulead VideoStudio 7's DVD-VR capture plug-in and browsed to
the Video_TS folder on the burned disc;

16. The burned MPEG file then appeared and it VERIFIED that the file's
audio was AC-3 DOLBY DIGITAL.

Those who claim they are unable to burn AC-3 audio MPEGs successfully
using VideoStudio and DVD MovieFactory fail because either...

a. they did not have their project settings set correctly;

b. they did not check the DO NOT CONVERT COMPLIANT MPEG FILES box;

c. they attempted to author the file from the VIDEOSTUDIO TIMELINE (a
method that will *not* pass the AC-3 audio through successfully);

d. they first EDITED the MPEG.

Any of the above four conditions will result in failure to pass the
AC-3 audio through successfully.

I have also found that some users of Ulead DVD MovieFactory 2 run into
a problem when they fail to find the advanced encoding options that
allow one to adjust FIELD ORDER.

To precisely match the FIELD ORDER settings, you may need to enable
the advanced MPEG encoding options in Ulead DVD MovieFactory 2.

On my Windows 2000 computer...

1. I clicked MY COMPUTER;

2. I clicked my C: drive;

3. I clicked the DOCUMENTS & SETTINGS folder;

4. I clicked the ALL USERS folder;

5. I clicked TOOLS > FOLDER OPTIONS and then clicked the VIEW tab to
make sure Windows would show HIDDEN FILES AND FOLDERS;

6. I clicked the APPLICATION DATA folder;

7. I clicked the ULEAD SYSTEMS folder;

8. I clicked the ULEAD DVD MOVIEFACTORY folder;

9. I clicked the 2.01 folder;

10. I clicked the DVDMF i-n-i file and then typed ADVANCE=1 under the
[VIODRIVER] heading;

11. I saved the i-n-i file;

12. Then I closed Ulead DVD MovieFactory 2 and re-opened the program.

Now when I enter the project settings, I see a new ADVANCE button
under the COMPRESSION tab.

This leads to the options to adjust the FIELD ORDER settings.

If one wishes to *edit* MPEGs with AC-3 audio, then it would be
necessary to purchase an application that officially supports AC-3
encoding - such as Ulead MediaStudio Pro 7:

or Ulead DVD Workshop AC-3:
