I have a DVD-Video formated disc with 15 clips. I have joined it in lots of 3 so I have 5 clips in total.
Originally recorded on a DVD recorder (JVC DRM10) in VR mode onto a -RW disc and then converted using MF4DC to DVD-Video format on a -R disc.
The DVD-Video formatted -R disc plays perfectly - nothing out of sync.
When I "Import DVD-Video" using this disc and then go through the "Add/Edit Media" part where you create menu's, I get as far as the preview screen and the audio is out of sync by about 3 seconds.
I have done a couple of discs successfuly in exactly the same way but now I seem to have this problem.
Any suggestions would be appreciated.
(Please write it out step by step because I'm not too familiar with alot of computer jargon)
I did try what someone else on this board suggested which was doing a fast export DVD compliant video but this created a file that then played no sound at all. Maybe something to do with my disc being AC-3?

This problem seems to have several different causes & solutions. Search the board for "sync", and you'll find lots of suggestions. Hopefully one will work for you.
A couple of notes about Womble - It is an editor only. So, you need to use MF (or another program) to author DVDs. And, at least one poster here has had sync problems after editing with Womble.
Womble has a tool that's supposed to repair corrupt MPEGs, but I haven't tried that feature since I don't get sync problems anymore. A couple of other programs that are supposed to repair MPEGs are VideoReDo ($50) and PVAStrumento (FREE).
That sounds like a corrupt-file problem. Your symptoms are slightly different than mine, but I discovered that my MPEG files were corrupted by editing (with MF3 and VS8). Note that MPEG files are not meant to be edited. Since, I started using Womble MPEG Video Wizard ($120) for editing, I have not had any sync problems.I have done a couple of discs successfuly in exactly the same way but now I seem to have this problem.

Re: Audio out of Sync - MF4DC
I too have had audio sync problems (like last night - argh 
) , but have stumbled across what I think might be a solution. It was in my case.
The audio sync problem seemed to occur when MF4DC re-encodes the audio to change the bit rate.
In my case I imported and edited clips that had audio encoded at 192 kbps. When I created a DVD from these clips using the default settings, MF4DC re-encoded the audio to 256 kbps, and inserted significant delay at edit points, for no apparent reason.
I solved the problem by changing the project settings to have the audio encoded at the rate of the original video clips, rather than 256 kbps. This is done by...
1) Find out the original audio encoding rate of your clips: right-click the clip, and select "media clip properties".
2) select the Project Settings button (or using the shortcut Alt-J), which is the button second from the left in the bottom left corner of the edit window: the one that looks like a gear on top of a film strip. This will result in a pop-up window labled "Project Settings".
3) click the "Change MPEG settings" button, which will create a pull down menu.
4) Select "customize" at the bottom of the pull-down - this will open a pop-up window called "Video Save Options".
5) Select the "Compression" tab in this window, and
6) change the audio bit rate settings to match those of the original clips.
When you create the DVD is should preserve the original audio encoding rate, and with any luck avoid the audio sync problems.
Good Luck!

mckinn- I believe the rate of my disc was 256 already, but I'm glad it worked for you.
phd - I have downloaded the trial of ViedeoRedo (but not sent for the key thing yet)
This is what I did, so maybe you can tell me if I am doing the right thing:
In Ulead with original disc I clicked on the Import DVD-Video button and imported my 15 files.
Joined them in lots of 3 so I had 5 in total.
Clicked on "Export Selected Clips" and 4 hours later when it was finished I opened up VideoReDo and "Open Video"
The 5 exported files were there as .mpeg files.
So I selected one of them and got the sync part working perfectly and "saved as".
I then went back to Movie Factory 4 and clicked on "Add Video Files" and added the file I had syncronised in VideoReDo.
I kept my original files there too.
Got as far as the preview screen and the orignals were out of Sync (as they were before) and the file I had synced in VideoRedo had no sound at all.
Am I missing anything or am I going about this in the wrong way?
The original file that was out of sync had these properties:
MPEG files
24 bits, 720 x 576, 25 fps
(DVD-PAL), 4:3
Video data rate: Variable (Max. 7000 kbps)
Audio data rate: 256 kbps
Dolby Digital Audio, 48 KHz, 2/0(L,R)
And the file brought over from VideoReDo is the same as above.
Is it anything to do with my files being AC-3 (Dolby)?

The AC3 should not make a difference. I use a Philips home recorder that has AC3 and have used DMF2LE (supports AC3 from MSP7), 3DC, and 4 with it without sync problems. I am in NTSC country. I also have a DVD camcorder that I use the mini RAM discs with as well.
I have a suggestion to streamline your process as well.
Get the trial key for VideoReDo so you aren't limited to 30 minutes output.
Make sure to check the option for "Output Streams FOr Movie Factory"
Use your original -RW disk. I believe you will find the .VRO file on it.
Copy the VRO file to your hard drive.
Process the VRO through QuickStream Fix.
If you have to edit the file, load the processed file back into VideoReDo for editing and save it.
Load the saved file into DMF. Make sure you have "Do not convert compliant..." checked.
Author the DVD to a folder on your hard drive and playback to confirm no audio sync problems.
Depending on the speed of your computer, It should pass the files through with no reencoding in less than 30 minutes. DMF3 used to take me 25-30 minutes for a full DVD. DMF4 authors to a folder in less than 15 minutes now! (P4 2.4 machine)
