Audio sync problem with DVDW2

YES!

Unfortunately, I do not have a solution, but sometimes it's nice to know that you're not alone. I use Pinnacle Studio 9 to make my .mpg's and then import them into DVDWS. The mpg's are perfectly synced. In DVDWS, I would be sure to select the same data rate as my imported .mpg, so that there would be no need for DVDWS to change the file. Now it seems that there is no way to do this, so DVDWS2 insists on going through the audio/video multiplexing process that is ruining my sync. Is it perhaps that my incoming audio is mpg audio, and DVDWS wants it to be LPCM? Hmmmm...... For the video's I'm working with that is not necessary, perhaps I can get DVDWS2 to leave the audio as it is....

Anyhoo, the problem exists elsewhere, and perhaps two posts will elicit some responses!

I've also been having problems with audio sync using Ulead Movie factory 2, and also Cyberlink Power Producer. I am using a Hauppage unit for capture, not the best for DVD, since the MPEG2 file has to be re-threaded before burning. The resultant MPEG2 file is always good audio synch on the PC, but after burning to DVD, there are synch problems. Direct from TV capture seems to be OK for audio synch, but VCR input (which uses the PC sound card for audio) gives a lot of problems after burning. Cyberlink Power Producer (version 1) gave good audio synch, but jerky video. Upgraded to version 2, good video, appalling audio synch. So far, Cyberlink have failed to explain. Ulead somewhat better, but not a lot. However, Hauppage allows you to record at CBR (constant bit rate) instead of the more usual VBR (variable bit rate); also by ignoring the Hauppage advice to re-thread using the provided Nanopeg editor, forces Ulead Movie factory to do the re-thread itself. The net result is not bad, a frame or two out, a bit like dubbed sound, but reasonably acceptable.
I hope this helps. There's a lot to this audio synch problem, and you would have thought the software guys taking our money would have sorted it out by now!

I am trialing DVDW and prefer Cyberlink VCR to capture movies from my analogue camera. If you are wondering why I use the Cyberlink VCR capture, it has noise reduction which makes my movies look better than the captures in DVDW trial.
Ulead DVD player replayed the CyberVCR files with jerky video & sound 100s of frames late. I then reset the advanced capture in VCR profile to IBP in frame window. (I did not know what I was doing except grasping for straws) The Ulead DVD player played the VCR file perfectly with the new frame settings. To shorten the story, I then did a test conversion to a DVD file on my HD, replayed sound in synch ok for the 30 min movie. PROBLEMS happened when I added transition enhancements to the original file and then made a DVD on my HD, sound 100s out and motion jerky & in rapid time. Tried importing the first DVD and inserting transitions, same Sound and motion problem when made to DVD.
Does any one have information or a link to an informative site on frame key info that may help me. I am reluctant to purchase DVDW until I get this resolved.

First of all, I am glad to find that I am not the only one to experience the out-of-sync problem with DVD Movie Factory 2. My problem is this: I have a Hauppauge WinTV which I use to capture my home video (Hi 8, analog). This TV card is excellent to record any TV programs in MPEG-2, and I can create DVD using Movie Factory without any major problems. In fact, sync is usually perfect. I had only one case which had a terrible sync problem.

When I burn my home movies using Movie Factory 2, I see the out-of-sync problem. As most of you said, it gets worse toward the end of 2-hour videos, but it is probably 2 seconds or so off. Not too bad, but bad enough to make me try to get it better again and again (I wasted 10 or so DVDs so far).

I tried to match the bid rate, audio, and so on to the original captured videos, but nothing seems to improve.

So, my questions to all:

1. Does Movie Factor treat TV programs captured in MPEG-2 differently from my captured home movies? These are identical as to the bid rate, and all encoding. Strange.

2. Any good solution? Do you see a better DVD authoring program out there? What I like about Movie Factory is that it is very fast compared to other programs, and also it has an automatic chapter creating function, which I really like.

Thanks

Well, I got into this thread at no. 4, and its time I shared my own conclusions. It seems that any system using the PC sound card could have problems, because the sampling rate of the card is incompatible with any of the DVD packages on offer. Each authoring program tries to deal with it in various ways, and fails. PowerProducer 1 succeeds with audio, but with jerky video, PowerProducer 2, and Ulead MovieFactory, are examples that produce out of sync. audio. My Hauppauge WinTV uses the sound card for VCR input, hence the poor sync I complained about.
But WinTV does not use the sound card for TV programs! So I can transfer TV programs to DVD without loss of sync. You can guess the rest; I don't use the VCR input to WinTV any more, I use the TV output of my video player into the WinTV Aerial/antenna input. Result is perfect synchronisation. If I use the "DVD record" option on WinTV the video on DVD is poor, I get line crawling with Ulead MovieFactory for example (I live in a PAL area, may be different with NTSC). So I record at the high quality level, MPEG2 12.0MBit/sec (CBR). In view of the sampling problem, I reckon Constant Bit Rate is the safest option. The software takes longer to render and write the DVD, but the end results are excellent.
I am sorry for all those out there who are stuck with using the PC sound card, but it does seem that the problem lies there.
