MF5 sound synch + restration key problems win dvd creator 3

21 nove 2008 - Here is the latest on the previous problems - it seems that seeking assistance on here was futile as the problems appear to be direct faults in the software!! We tested both Ulead 5 and WIN DVD 3 on different PCs here in France and the UK with both win2000 and XP with the same problems - here is my letter to Corel support - after all they did was pass it on! I shall look at Adobe premier now - !!? I note that no further comments or help were forthcoming here?

Hello - please look back at my letters to you re Ulead 5 and Win DVD Creator3 ? I stated that Ulead5 gave the same problems on XP not just win2000 pro with the sound synch problems doing NTSC? Also on several PCs in Eupope we tested it on! We are pleased to say that Ulead 6 works fine on XP with no out of synch sound for NTSC! 5 is crap, 6 one step up!

Next and far more importantly. Now I have XP running and re tried the WIN DVD creator I have paid you for - PLUS have had a friend in UK also try it on XP - WE HAVE FOUND THE SAME PROBLEMS PERSIST on both of our PCS which you must be aware of from other clients ?!?!? It is clearly a software problem from your end and asking us to change out settings - kitchen sink and all is not the point - it requires an update and patch from you please?!?! The problem remains - all works well until a second menu plus are created and then none of these will save!! So unless one burns immediately without problems then all menus are lost! This is not possible if changing formats from PAL to NTSC as usually another glitch occurs and sound is lost in doing so after one burn! Please respond that you will create an update to stop this problem and allow a full save of menus?? At present the software is not, fully, fit for the purpose it was purchased for and you promote.

Peter,

These annoying "lip sync" problems seem to have many different potential causes & solutions.

I'm 99.9% sure this has nothing to do with your soundcard drivers (or video drivers), or your hardware. All of the "work" is done by your CPU, and if you're not having problems with any of your other applications, your hardware is OK. Most likely, this is either a software problem (probably a CODEC), or there is some corruption in your original video file.

It's not unusual to have a corrupt video file that plays back fine, but causes trouble when you try to edit or convert it. This kind of problem is most common with more-compressed formats. Different CODECs may be better or worse at handling corrupt files. If you are converting to MPEG-2 from a different format, sometimes you can get around the problem by using a different conversion program.

As you may know, the audio & video are separate "streams" multiplexed (interwoven) together in the audio/video file. Apparently, Something is going wrong during the transcoding process where your audio & video are de-multiplexed, converted to DVD-compliant audio & video, and then re-multiplexed.

Just as an example of what might be happening... Imagine that you have a video frame with some bad data. The bad video frame may be thrown-away, while the associated audio remains. When the audio & video are re-multiplexed, you have a sync problem.

And, since this would be a "major upgrade", I would encourage you to try-out the competition too! (We are not Corel employees here, so we don't mind if you find something else that works better for your particualr situation.)

Like Steve said, tell us the format of your original files and what kinds of things you are doing with them. (I assume you're making some edits, and making a DVD?) Hopefully we can help you.

Doug.
