Recorded DVD out-of sync audio after Nero burn

[rckowal]

Since changing to a new computer, I'm seeing poor lip synch on DVD movies when they're played in a stand alone Sony player. They were originally recorded on a DVR, edited then burned with Nero. The synch seems to be worse when the backup first starts to play but improves a bit (to near normal) as it continues to run.

MY QUESTION: What can be causing this & how can I fix it?

These DVDs were made by recording a movie from cable TV using a Liteon DVR - which records in DVD_VR format. It was recorded to a Memorex DVD+RW. DVD Decrypter was used to open the DVD_VR file & store it on a hard drive as VTS files.

It is then opened in DVD Shrink 3.2 (which doesn't open DVD_VR) where it is lightly edited to cut several minutes of extraneous clips (commercials) captured just prior to & following the movie. Usually, the movies are short enough so they do not need to be compressed (or analyzed) to fit on a DVD+R. Once edited, they are then burned by Nero 7 from within DVD Shrink using the (auto) backup button. Media is Verbatim 8X DVD+R. The hardware is a Phillips 8701 burner.

In (limited) tests done, the original DVD_VR; as well as the & the Nero burned DVD, both play normally on the DVD drive in the PC (Power DVD, Nero Show, Windows) &/or the DVRs playback mode. So it appears that the issue may possibly be some incompatability with the Sony player. What is baffling though, is that a number of movies made using the exact same process (but different hardware & Nero 6.6) never had poor lip synch when played on the same Sony stand alone player.

Some help/guidance from the knowledgeable on the forum will be very much appreciated.

Thanks for replying setarip_old.

Yes to both questions.

In fact, even media from other batches - including TDK, Verbatim & Memorex brands - still play properly (& always did) on the same stand alone player.

If it means anything, there are three different Sony stand alone players in the family. All of them always played all DVDs in synch that were made during the past several years.

You might want to experiment by going back to NERO v.6.6...

>>Yes on two of them. The third Sony is at a distant location so I can't get to it now.

>>Are you suggesting that possibly Nero 7 may be the cause? If so, how might it differ from 6.6?

[setarip_old]

Are you suggesting that possibly Nero 7 may be the cause? If so, how might it differ from 6.6?I'm suggesting that anything is possible - and the way to track down the cause of a problem is to eliminate each possible cause, one at a time...

[rckowal]

OK, I'm following your "process of elimination" logic now.

I just discovered some thing which casts an entirely different light on this issue. I took one of the original "raw/unedited" DVD recordings, edited & burned it using the old PC/software/Nero 6.6 (which I believed was working well).

Very much to my surprise, this freshly produced DVD had "stand alone player" asynch as well - even though it was made using the same process & hardware as dozens of its normal playing predecessors did.

This suggests that some thing may have has changed in the DVR capture. I'll have to back track to see if I can figure out what this might be.

Do you have any ideas to offer that might help me to narrow it down???

[setarip_old]

edited & burned itTry burning WITHOUT editing - and see if it still produces an asynchronous DVD. If it's NOT asynchronous, your problem is probably arising from your editing...

I'll try that to narrow it down further.

By the way, I looked over the audio settings on the DVR. I noticed that it was set to "bitstream" - which the manual says is for digital audio output. The other option is "PCM" which is for WAV, etc. files. Since I'm not using digital audio, I reset it to "PCM" & am now recording a new test capture. I'll let you know how it, as well as the "unedited" burn turns out.

[setarip_old]

I'm fairly certain that setting it to PCM will resolve the anomalous behavior...

That's encouraging. I'm recording another movie with PCM set. The other one had a fault & would'nt open one of the VOB files.

Hi Setarip_old,

Well it appears that the "Bitstream" audio setting was the culprit here. Since resetting it to PCM a newly made, and edited, movie is playing normally on both of our Sony players. Even my wife, who has a sharp eye for anomalies of this type, has given "two thumbs up" to the new test DVD. I'll have to try more of them to be completely certain that all is really in control, but things are looking pretty good right now.

One more question: Is it feasible to some how redo earlier master recordings with poor synch? If so, what software would you recommend? There are a few that I would like to save - if possible.

Thanks for all of the time you gave to guide me through this maze. It's really much appreciated.
